This demo is not really about TicTacToe, I was experimenting with a natural handwriting interface. I was inspired by the use of handwriting and drawing in Brain Age for the DS, and I wanted to create something similiar.

In this demo, you have to draw an "X" or an "O", and the game will recognize which you've drawn. If you run into trouble, click "erase" at the bottom.

Everything is written in ActionScript. In addition to the shape recognition, it smooths the shape while you are drawing it, draws everything through primative drawing code, and has some basic AI. There's over a thousand lines of ActionScript code, only a hundred or so are involved with basic TicTacToe gameplay!
