After long hours staring at my screen figuring out what went wrong where I think it's finally time to release what I've been working on the last couple of days. There is still lots to put in and refine but it handles basic operations very well.
Inspired by the handwriting calculator from nokia labs, I started working on this, never knowing that it would turn out much and much harder than I first expected.
Features:
Basic math operations: (+, -, *, /, ^)
Multi-digit support.
Handwriting recognition (now using graffiti).
Undo/erase last input
Still to come:
Multiple gestures for a single operator.
Parenthesis.
Custom graffiti
