Sharing Obsessions

Week #6

Hey, it is February the worst month of the year and despite its weather, I have great personal news. I started at HOLOPLOT as a Product Manager. The company is developing new technologies (wave-field synthesis and beam forming) in spatial audio, and challenging what can be done with audible experiences. I’m thrilled to finally connect these two universes in my life – audio and technology.


A great twitter thread on different and very useful Google Sheets formulas. If there is one skill that I'm very happy to have built is to be able to work well with Excel/Sheets. VLOOKUPs and SUMIFs are your friend.


Slit Scan Photography

Slit photograhy is one way to add a third dimension to still images. Not depth, but time. This article by Golan Levin is a catalog of video and photographic artworks using the technique.


Here are a couple of other links.

Matt Round used GPT-3 to create poems as written by 8-bit computers.

ZX Spectrum

I am a machine,
a simple machine
But I feel love, the burning love.
For the programmer who created me
He is my everything, my world.

If you want to play with GPT-3, head over to Thomas Haferflack’ Pollinations project.

Week #1

Retro tech, Soviet Cartoons, and Dithering.

Hello and Happy 2022,

I first wanted to share a some personal news. This will be my last month working full time for Envisioning. After ~ 8 years, I thought I could profit from some new challenges. I’m leaving the day-to-day operations, but will continue close to the team. Soon, I will share more details of what I will be doing.

Back with the regular schedule :)


On this week's episode of retrotech: Video presentations or slideshows are things we take for granted. I never actually thought about its development or existence before GUI or computer projectors, yet they existed in a hardcore-tech-fashion since at least the 1980s. All done using slide projectors – yes, you’ve read it correctly Slides.

This article (actually a long-read keynote with pun-full slides) written by, one of the technique’ pioneers, Douglas Mesney documents its evolution from a simple 3-projector-array concotion, to bespoke programming languages with 100 projectors and 21 screen arrays.

This video shows what they could do with a 15 projector array.


On Soviet children cartoons: as Winnieh-the-Pooh, Bambi, and other works from 1926 are joining the public domain, it is a good opportunity to revisit and share some Soviet remakes and other impressive cartoons from the era. They have a different approach to the western classics we know. Not only in style and aesthetics, but the whole delivery and narrative. I wonder how differently I would’ve perceived things growing up with such distinct imagery.

The Hedgehog in the Fog

Elected the “#1 Animated film of all the time”, tells the story of a Hedgehog going to meet his friend Bear. He journeys through the forest and is tormented by an owl. Here is an english version.

The Little Mermaid

Rusalochka – the Little Mermaid – trades her voice for legs after falling in love with a human prince. Here with English subtitles

There is also Vinni Pukh (Winnieh-the-pooh), Nu, Pogodi! (Tom&Jerry), Alice in the Wonderland, The Scarlet Flower (The Sleeping Beauty), and last but not least Krokodil Gena & Cheburashka(whose rights were later bought by Japan).

Disney’s fight to extend Mickey Mouse’s copyright is quite extensive. In two years, the Steamboat Willie will join the public domain too, meanwhile this article sheds a good light into it.


Return of the Obra Dinn relies heavily on Dithering

This ObservableHQ experiment on different Dithering techniques. Dither is a technique that is applied all around us in the digital media we consume: photography, video, and audio processing. The experiment describes and walks you through the different frameworks and results.

Born as technique to deal with limitation (pixel amount, color gamut, etc…) it is been transfered to an aesthetic style. The fantastic Return of The Obra Dinn relies heavily on this to achieve its looks. If you don't know it, it is a wonderful game created by Lucas Pope (he also did "Papers Please") and is available for almost every console / OS.

See you next time.

Week #29

Tell me you've been to Italy without telling me you've been to Italy.

I couldn't put a finger on how I felt looking at these street food menus in Milan's Chinatown (this explains it better). 

Arriving in Italy during the semi & final of the Eurocup was as puzzling as looking at those translated dishes. Both evenings that the Italy team played felt like a breach in the current timeline of events. I had my temperature (!) checked throughout the day with Thermo-guns, but everything was forgotten after 8p. After countless aperitiv during this week, I'm back with my normal schedule. This week we have a lot of A.I. posts.

Aftermath of Italy's classification for the Finals.


Perceptions of Probability: What people mean when they use everyday terms describing probabilities. I wonder what would be the Portuguese & German equivalent.

Sherman Kent, the first director of CIA's Office of National Estimates, was one of the first to recognize problems of communication caused by imprecise statements of uncertainty


GAN Theft Auto is a Generative Adversarial Network that recreates the Grand Theft Auto 5 environment. In other words, the video below shows the result of training a neural network with an enormous amount of data from the GTA 5 game. With this model, they were able to recreate (parts) of the game without writing a single physics line of code or creating any 3d models. Quite impressive and good example of how you can use synthetic data to train models.


I remember reading a couple of articles years ago stating that "no interface was the best interface", making some connection to the advantages of voice assistants (imho, meh). A year after OpenAI has opened the API of its powerful GPT-3 AI model, we will soon be seeing more frequent implementations, is a good example of such practical cases. You can see a video of it in action here.


That is a hippopotamus

One fascinating science theory that I've been bumping into every now and then is that the way we depicture dinosaurs is completely inaccurate. Here are several links with different takes on this topic [1] [2] [3]. I don't think we will ever get to the truth in that topic, but I found this article depicting current animals in the same way we depict dinosaurs.

Sketches reveal what animals would look like if drawn like dinosaurs
Palaeoartist C. M. Kosemen believes there was more to the shapely dinosaurs, including larger layers of fat and areas of soft tissue. He blames Hollywood for dinosaurs’ ‘monster’ image.


A Physalis painted with Quinacridone Gold PO49

We ran out of Quinacridone Gold and I loved reading about it. Apparently the manufacturer of the goldest of golden pigments ceased its production decades ago, and sold all of its leftover stock to another ink manufacturer, Daniel Smith. We won't have any other paintings in our lifetime with this hue of gold.

The way I learned about this was by casually browsing this eshop. It explicitly disclaims on the page:

GOLD is now available to EVERYONE* (except Daniel Smith who have bought up all available Quinacridone Gold pigment and made it extinct so no other paint makers or artists can use it ever again!)
IMPORTANT -  By adding Gold to your cart you confirm that you are not Daniel Smith, you are in no way affiliated to Daniel Smith, you are not purchasing this item on behalf of Daniel Smith or an associate of Daniel Smith. To the best of your knowledge, information and belief this material will not make it's way into the hands of Daniel Smith.


Carlos Cipa - Retronyms (2019)

Carlos Cipa's was the first concert I've attended since March 2020. A beautiful landscape by this Munich-based composer. His piano performance at Silent Green was delightful. You can find it here.


Week #23

Common reflections, couple of cool tools, and beautiful guitar music.

Common Reflections – False Knees


Not so far away

We can only think about the future from today's perspective. "Closer Than We Think!" created by Arthur Radebaugh was a comic strip from the 50s that imagined what the future would look like. This twitter thread has a good collection of them and there is also a documentary available here.


Brilliant blew my mind away. A great way to teach math and science with interactive exercises.


Flow is an experimental image editor that shift pixels around in horizontal or vertical bands. It was created by Constraint Systems, if you don't know it, check the site and you won't regret.


This NY Times documentary on the daily life of a professional live streamer in China is as present dystopian as we can get.


This is one of those threads that just keeps on giving. I had no idea about any of it, now I can't wait to watch the next performances.


Fabiano do Nascimento – Tempo dos Mestres (2017)

I haven't stopped listening to this record by Fabiano do Nascimento since I it was recommended to me. You have a lot of choro, samba, and jazz. You can see him performing on NPR Tiny Desk with a humongous 10-string guitar here.

Um beijo.

Week #21

Hello Sun, it is nice to see you again, wait… why are you leaving already?

This article on the Brazilianization of the world by Alex Hochuli. A great read on the current political landscape intersected with the history of Brazil.

The Brazilianization of the World - American Affairs Journal
The West’s involution finds its mirror image in the original coun­try of the future, the nation doomed forever to remain the country of the future, the one that never reaches its destination: Brazil. The Brazilianization of the world is our encounter with a future denied, and in which this frustrati…


João Bosco - Dá licença meu senhor (1996)

João Bosco! I can only appreciate it, but I cannot comprehend how good his rhythm notion is. This record is packed with pieces of our traditional repertoire with unexpected twists – Caymmi (O Vento), Gil (Expresso 2222), Jobim (Desafinado), Rosa (Um gago apaixonado), and Barroso (No Tabuleiro da Baiana).  You cannot deny that João is definitely having fun. My current happy song is "Se você jurar". – Album on YouTube or Spotify.


Photography prints
Buy art from your friends. It is an excellent way of showing them your support, and you get something beautiful to hang on your wall. Here is a selection of photographs ready for your home.

After the photos from Brazil, some of you asked for prints, and for those interested, I made this page (thank you Flavia, Daniel and Noa).
