Here's what I want someone to develop...

I want someone to develop a bunch of scratch off "lottery-style" tickets where you can buy a batch of them. Then you give one to your OT kid near the end of a session as a reward. They have to scratch it off with a quarter (a great fine motor/strengthening/visual attention task) to get to the code underneath. Then they have to input the code (like X3A-4BX-2AY) into a website at www.otreward.com or something (a great copying task). Then, a random silly thing happens once they input the code, like a 3 minute song or dance or funny joke.

It would obviously be a lot of work so it would never happen, but wouldn't it be cool? :)
