This is so neat, I love the neon particle trail effect. Can make some cool looking patterns.
Once of my attractors got stuck at maximum repulsion, just vibrates when I press the button.
Thanks! Ah, and now I see a bug in the attractor resizing-- I'll have to figure out if I can fix it within the 5 characters I have left...
Basically, when the attractor is at max size it changes the direction of what the resize button does-- but if you happen to stop resizing exactly at max size, it sits there changing direction back and forth 60 times a second, so you only have a 50/50 chance of hitting the resize button on the right frame to break out of that loop vs. further growing it.
Update: I think this is fixed now. 560/560 characters used.
