JSGrafix Sandbox (JSGS)

Square After-Image Challenge

Observations and Hints:

Seeing things that are not there?

Can you find the code that makes the light square image within each cluster of TNTTwoTonedDisks? If you can, you're a better coder than us, cuz those squares are just not there! It's another illusion!

Can you make it?
