Share My Creation Boingle - Simple path tracing time waster

This game I just had to put out there. I would like to improve it by using random drawn splines versus the straight lines. This is the single player version and I am almost done with the next release which will allow two players. One to draw the path, and then the other player has to follow it.
If any one has code for drawing a spline through 8 points please let me know. Doog
