Illusion with AnimGif encoder Javascript

There have been some implementations lately to create gif89a with the new webworkers.
I didn't get round to it, because I wanted a clean version (with a workaround for older browsers), and frankly because I have been a bit under the weather and had other things to think about.

But yesterday I said to myself I had to get back in the saddle. So this is the first thing I tackled.
I wanted to have a nice application, where you can convert game-footage into animated gifs smoothly. And to test it, I generated this small illusion. Enjoy.
If you stare at the middle a while, things will start growing when you look at them.
Also, I just like the confusion around the stripe.. If you look at a single wind of the spiral, you'll see it appears not actually to be moving to the middle, it jumps back.. The animation seems not to be smooth.
However, when you look at the middle, the spiral seems to be continuously moving inward
and the animation is smooth again..


In fact, for a good test, I wanted to render something with a lot of color. (gif89a being a 256 color format) So here is another one, but with changing colors. It makes the illusion less effective, but it's better for testing..
