Was always fascinated by Hilbert curves.
I knew Bridget Riley’s work a bit before going into the exhibition because she was one of the visual artists you learn about when you study 20C music, and so I had seen a few of these op art pieces, but I never expected an illusion to work so well on such a huge scale.
I always found it fun that she really wasn't happy with how that 3d piece worked out, so went back to flat canvas for the rest of her career. I'm with you though, I thought it was amazing.
Here's a great documentary on Riley for anyone with BBC access: https://www.bbc.co.uk/iplayer/episode/m0011psx/bridget-riley...
The works that most pleased me most were the later colourful wall paintings like Rajastan (2012). Painting directly on the gallery walls makes for an interesting copyright / art-as-property type question. I guess her team has to repaint them wherever they are shown and must oversee their destruction too. Feels like there could be a Star Trek transporter glitch type issue and whoops, we now have two Rajastan (2012)'s.
That hints at a totally impractical way to do that with regular etch a sketch: put a strong magnet on top of the screen wherever you want the image to be retained and flip over the device.
Where you put magnets, eddy currents will be induced into the aluminium dust. Those will generate a magnetic field that slows down the particles, as they drop towards the screen.
So, if wait just long enough, and flip the device back, you can prevent those particles from reaching the screen.
Problems/challenges:
- “just long enough” will be very tricky to accomplish
- you probably will need very strong magnets
- it will be a challenge to have well-defined regions where your magnet(s) don’t affect the screen
⇒ I guess it may be easier (not easy) to cool your etch a sketch to -196 °C and use a strong magnet (https://youtu.be/zU3niMdjegQ?feature=shared)
Easiest probably would be https://hackaday.com/2024/03/27/sort-of-electromagnet-attrac... (likely still impractical for the distance needed in an etch a sketch)
Side note on magnets: when our kids were young, I got one of theose stick-and-ball magnetic sets that are capable of making geometric figures. So I made a Archimedian-style polyhedron big enough to be a helmet. I wore it for some minutes on a few occasions and it gave me a very unpleasant (but subtle) headache and a deep, somewhat lasting nausea.
I try not to put magnets near my body anymore, nor allow the kids to. My understanding is that our bodies were evolved over millennia without being near magnets (or electric fields), especially the neodynium sorts.
Anyhow, thanks for the thoughtful reply. It's the best of the internet's potential.
Another interesting thing about such connections is trying to find a mention of them both in the same media (web page, research paper, etc) so thanks to this a very promising book is found "Art, algorithm and ambiguity. Aesthetic ambiguity with regard to metacognition based on visual semiotics, visual rhetoric and Gestalt Psychology" by Axel Rohlfs [2]. This method sometimes works in other fields, if a researcher is aware of a couple obscure facts, names or entities in a field, he or she is usually very good at the field or at least dedicated enough time to it

Rants aside, thats quite a gem to surface here.
Wondering whether for single line drawings there is any analog of aperiodic tillings.

Reminds me of the graphic design at "May Contain Hackers 2022" that I really liked: https://mch2022.org/#/ which included a tool to generate similar designs https://mch2022.org/design/
Also reminds me of Bernard Cohen works that I loved in Tate Modern. For me, he achieves something next level which is to go beyond just pressing my "pleasing geometric pattern" buttons but also the type of order/disorder that feels like a human intelligence at work too.
I can't find a page including the ones I have in mind but:

Sod it, this is probably more comprehensive:

Not quite on the same level, but I think the essence comes through.
Anyway, I just finished looking at all your works on display this morning. Such beautiful arrangements of patterns and colors.
Thank you for posting, I'm in awe!

I don’t think I’ve ever connected so strongly with a gallery exhibit as I did for Wacław’s artwork. Something about how intricate the works with just a single line. It was such a serendipitous moment that I won’t soon forget.
