I've been thinking all week about the work that @kandid@chaos.social published last week. The spiral is particularly fetching. I want it to see it rotating and tried animating it, but it turns out that the barber-pole illusion makes it very difficult. (https://jov.arvojournals.org/article.aspx?articleid=2121451#:~:text=When%20the%20cylinder%20rotates%20about%20its%20axis%2C,a%20rectangular%20modulator%2C%20so%20that%20the%20motion) This is just a test. Again, the original picture is by @kandid@chaos.social. Kudos to Thomas for his wonderful work. https://elk.zone/chaos.social/@kandid/116268302802168347 #cavalry #animation #experiment
