Seeing @neauoire's paper computing explorations, I was reminded of an old idea I proposed at PaperCamp LDN back in 2009: Originally this was vaguely about using origami to create multi-purpose AR markers, but I then extended it to other use cases, some of which could be adapted and be even relevant today, e.g. as a form of proof-of-work, protection against AI crawlers or other form of access control.

Some possible approaches for different use cases:

1) Ask users to perform or series of simple folds and then check results by validating fold lines in the flat sheet paper via computer vision
2) Same as #1, but perform shape recognition/validation of fully folded result
3) Unfold a pre-shared (and pre-folded) origami object to check result by validating fold lines via computer vision
4) Provide instructions for multiple origami creations to create uniquely identifiable objects for computer vision based interactive environments

Number 1-3 are more or less about forms of proving physicality, work, membership. Number 4 is more about using origimi as fiducial markers for general interactions

More ideas/summary from that event:

Screenshot excerpt from Jeremy Keith's blog post about PaperCamp (linked): "Karsten Schmidt begins by talking about print on demand. He shows beautiful computer-generated algorithm-driven book covers from Faber Finds. He then shows the most gorgeous unique identifiers I’ve ever seen. These are printed on to postcards for the end of year show at the London College of Fashion—one per student. These cards are machine readable at interactive tables. But what about generating machine-readable identifiers without using a machine? Right now you still need a computer and a printer. What if you could use origami instead? If you think about it, that’s what’s going on with Edward James Olmos’s unicorn in Bladerunner. Take a piece of paper, configure it in a certain way; now it contains a machine-readable message."

New article explores the work of Nestoras Papanikolopoulos, a pioneer of digital art in Greece since 1984. A vital step in recognizing early computer-based art and its marginalization in official discourse.

To avoid a massive OpenCV dependency for a current project I'm involved in, I ended up porting my own homemade, naive optical flow code from 2008 and just released it as a new package. Originally this was written for a gestural UI system for Nokia retail stores (prior to the Microsoft takeover), the package readme contains another short video showing the flow field being utilized to rotate a 3D cube:

I've also created a small new example project for testing with either webcam or videos:

Just published my latest tech dive:
"What a Week: From Quantum Particles to Team Red"! 🚀

Been losing sleep over Veo 2's computer vision breakthroughs (finally affordable for indie devs!), Microsoft's hunt for Majorana fermions (quantum computing's holy grail?), and AMD's continued market disruption (though seriously, their marketing dept needs work 😅).
That video on AI consciousness sent me down a philosophical rabbit hole that I'm still navigating.
The line between advanced pattern recognition and "awareness" gets blurrier every day...
These seemingly different technologies are all connected pieces of the same revolution. Most exciting innovations happen at intersections!
