Demo video for a program written on my iPad using Codea.
The program draws several balls floating in a 2D space, the color depends on each ball's speed (blue to red, as speed increases)
You can tap anywhere to create a new attraction point (white circles) that slowly fades away until it dissappears. You can also drag attraction points to relocate them.
