INNOVATION- Leap UDK In Action

Couldn't resist posting a video of the Leap in UDK. I simply hooked up a particle effect to the Hand Position and set up some conditions so that the colours change depending on whether the users hand is open or closed. Haven't figured out how to change the colour of the particle trail yet but that is the main focus: I'd like the user to be able to draw in different colours by using their hands.
