Fractals are the new kaleidoscopes. My parents had this wooden one that the bought at a Renaissance Fair and you could open it up and put anything inside you wanted to. It also had a prism type glass you could attach to make things look different.
Fascinating! Had no idea they were selling anything like this. I’ve been wracking my brain trying to remember where I did a video on fractals back in the VERY old computer days. I talked an IBM VP, head of research, into getting me out of computer languages and he gave me an international multimedia magazine. I was also his personal video maker and I’d make little music videos for him to show when he was giving keynote addresses, when I didn’t have time to make him a full video. One video was made in the middle of the night because TA DUM!!! We could put video on a computer monitor. Okay, so bugs let other video pop up in the middle of the images but it was MOVING!! Boy that was a long time ago. Husband built a half million dollar studio around my project and I learned to edit on 1” broadcast machines that we dragged out of virtual reality projects. With no edit controller! Until husband wrote one.
