Understanding the dynamics of pygame… would a simple mode that looks something like this [https://www.dwitter.net/d/13956](https://www.dwitter.net/d/13956) be possible to code for the ETC?

I know this example is in javascript. I’m just wondering if it’s possible.

It looks similar, but it is different. My zoom effect copies the image, so the colour movement goes from the outside / front to the rearground / center. But in this visual the colour moves from the rear to the front.  
I am not into Java Script, but to me it looks like they hand the colour(=style) though an indexed list, like a fifo.

I did a short search and found:

For an example see the third answer in this posting.
