Ever want to practice microPK? Here's a quick and simple game to do exactly that. 

A bunch of circles are set on a plain background, and a simple java script thing sets them to moving about in a pseudo-random manner. 

Your task? Get them to co-operate to form a larger circle of dots on the field of play... exact size is up to you.

"Fast" has more jitter in addition to more speed.

(The screenshot is from an earlier version. Only the button has really changed, though.)

Have fun :)
