Fairly self-explanatory, but here are some rules:
create an effect that follows the cursor in some way or another.
no length limit, use as much code as you want.
post as many times as you want.
be as creative as possible, think of something you haven't seen before and try to make it.
most importantly: have fun.
you don't have to be an expert to create a great effect. beginners are encouraged to participate. this might help ease the learning curve:
// create listener object
mouseListener = new Object();
// retrieve the cursor's current position
someObject._x = _root._xmouse;
someObject._y = _root._ymouse;
i will throw together a few examples. i have attached two for now.
