All done. A few hours late, but I really think it was worth it. This let’s you generate “radiation patterns” by changing the speed of rotation and lenght of the segments, click the question mark in the lower left corner for help.
It can draw all kinds of stuff, like:
A rocket: -1:50:3:50:-1:50
An owl: -3:50:-1:50:2:50
A heart: 1:40:-1:40:3:40:-1:80
Post your own patterns in the comments!
