the following is a message from my daughter who works for Nintendo:
I would guess that the movement of the cursor onscreen is interesting to him (like a laser pointer). Eventually, he has come to associate that with the console and he either likes it and wants you to play it more.

I would highly recommend buying a LOT of games, to see which ones he is most interested in. Particularly those titles published by Nintendo, such as Wii Play, available February 12th!
