This is a work-around because Gimp Chat doesn't support HTML5 animation.

nice!

tas_mania: Wow! You put down a lot of work on that one, didn't you?! I can't do animations at all, so consider me overly impressed, hehe.

Nicely done, Tas.

If you had more of these type of silent video clips, you could combine them all and then use some funky sound track like the old days when they had computer generated graphics to dance songs.

Hi guys, I'm glad you liked this one. AnMal said
Actually no.
I discovered how to automate the process.

The 'comp_mix' box is like a sound mixer except it works with images.
I used MathMap Composer which was first demonstrated 8 to 10 years ago with still images. But hardly anybody tried it with animation.
Maybe their computers were not powerful enough back then?

Composer combines all the elements into one page of sliders and options. You have as much time as you like to get the effects you want.
It's just like using a music synthesizer! When happy apply to multiple layers and you have an animation.

I've found there are other mixers including ones with double feedback and I haven't yet tried the many filters with animation.
Disclaimer. I'm the current maintainer of Mathmap but most of the C code is beyond me. I stumbled on this process after watching an old video by the MathMap coder Mark Probst.

Nice work Taz. Good to know you haven't given up on MathMap.
