Read instructions below first, then draw a shape here to start...
(Not working on touch devices at the moment)
Start by drawing one of shapes shown at the top. The guess-a-tron will hightlight the shape it thinks you've drawn.
It'll probably get it wrong, but with your help it could be better. If it gets the answer wrong click the correct answer to train it.
Draw as many shapes as you like. If you keep training it'll get more accurate.
