Ok as promised here is Flash version with 12 effects.
Funny that flash with 4 million of colors and 12 effects wights 7Kb while Gif with 1 effect and 32 colors weights 14Kb
Mmm. Actually some effects are lame I remember having better ones in a process of making but kind of lost them
And on a side not it is not truly an animation
I haven't drawn a thing
Just picture analysis where I filter, move, change color of picture pixels based on their position and color. Tough still a lot of code...
