I have this program that I have written a month or so ago and I want to make the applet animate the plotted points. Basically show the shapes being drawn in real time instead coming up already done.

Is there a way to make them change colors randomly?

I also, want to make it loop drawing random things everywhere any suggestions?

I was trying to use the timer, but I really dont understand how to use it.

thanks
