Heh if it was for my kid how about a modern version of Rocky's boots.

I learned this stuff around 10 playing that game and didn't even realize what I was learning cause it was fun.

But it definitely worked.. I aced every class I ever took that required logic right through college with ease. Both hardware courses, CS courses, and a philosophy course.

edit:

Here it is!

I may very well sit my child down in front of this next time he says he's bored with the typical kids coding things.
