I just tried your app. Accuracy seems poor -- almost like a mini-game rather than a useful tool. The concept is very clever, though.

So, zooming doesn't solve your accuracy problem? Did you use a graphics tablet or an iPad?

I used the desktop. I don't think I should want to zoom to draw an element because I would just have to move my fingers further.
