Request for graphical NIM on Prime

[Joe Horn]

The recent discussions about the game of NIM in the other forums here makes me wish that somebody would write a graphical NIM for the Prime.

Concept: You tell it how many piles, and how many stones in each pile, then it displays the stones (in rows) and lets you drag them with your finger across the screen. It takes turns with you, and the one who drags the last stone across loses the game. No numbers on the screen; just stones. That'd be cool.

As a kid I memorized the 4-5-6 game, but only learned the general "nim-sum" strategy much later. Fascinating stuff.
