Made with pre-multitouch app (used my iPod that can't update) so you'll have to adapt it yourself.
You swipe your finger and it creates a right triangle, the hypotenuse being a line from the beginning to end of your touch. If you tap your finger it will toggle whether measurements are shown or not.
I thought this was a really cool but simple program, could potentially be used as a draw example program if adapted to multi touch (hint hint nudge nudge Admin )
