I recently had fun implementing [0] some of the concepts/math for ambiguous cylinders by Kokichi Sugihara. Some of his first illusions [1] came from researching computer vision, where the computer should understand how a 2d picture supposedly looked in 3d. When feeding it some optical illusions, he realised it would be possible to make these objects in real life!

The direct links to the stl files in github let you rotate it around and get some idea of how they actually work [1][2]. This is absolutely mind-blowing!

I don't get the first one but squaring the circle is cool
Wow, the best illusions I’ve seen for a while! Thanks!
Sugihara just recently (again) won the Illusion of the Year contest. He has made lots of fun stuff over the years that's worth checking out! [2]
I was lucky to attend "FUN with Algorithms 2018" earlier this year, where he was one of the invited speakers. Seeing the illusions IRL blew my mind and I had to make them myself.

Should be watched for just the music itself! ;-)
