First of all, I didn’t know where to put this post. I did it here because I’ll implement this on AS3. If it’s wrong, please move it to the right place.
Well, I’ve been requested to do some interactive pieces like these:

It has a projector on the ceil, and the events are generated by the shadows. The client told us that we have to do it with mouse events. What I don’t understand is if they are mouse events, what happens when there are multiple users casting shadows at the same time? How does a “shape” (the shadow) generate mouse events?
