If you draw brackets from bottom up they are recorded inverted.

For example, } drawn from bottom up is "recognized" as {.

That's because it's rotationally insensitive, which is a rather interesting property. I'm not sure how useful it is, but it certainly surprised me.

When I used this code for a simple application, I made a small change to the recognized to limit the rotational invariance so that a gesture that was rotated more than a certain angle threshold would not match.
