Lego Vision Command

So I bought this #9731 Vision Command set maybe 3-4 years ago from eToys when they went on clearance... I'm still kicking myself for not buying 4 or 5 of them, instead I only bought 1 at the time.

So I connect it to my iMac at work, downloaded macam 8.5 and iChatUSBCam, copied the macam.component into /Library/Quick Time/ and managed to get it working with iChat... Very nifty! The iChatUSBCam is a $9.95 program -- I'm thinking about buying, otherwise it doesn't work with iChat.
