I've been playing with the Multitouch object and I was just wondering what's the best way to implement an idea:

If I have 3 objects which I want to move around, how can I make it so that you can 'pickup' each object and while you're still touching it, make it stay at the finger you're touching it with?

So if I have three squares: A,B,C and three fingers: 1,2,3. Then if I touch and keep pressing A with finger 1 want it to stay at finger 1 while at the same time I want to touch B with finger 2 and have it stay wherever finger 2 moves, and so on.

Thanks.
