This is a quick demonstration on how to finger-paint with Leap Motion. You can use a brush if you prefer it to your fingers, but the result won’t change much. What I realized while watching this demonstration live, was that it obviously takes a while to fully control the device and the actions that trigger effects, like showing both hand palms to bring up the editing tools box.

The question about integration with Photoshop and similar types of software still remains, since it might need that companies and developers program their creations to allow Leap Motion interaction.
