Community Toolkit

Bringing cutting-edge technology to the classic Christmas lights display. Using the Leap Motion Controller and an Arduino board, Kaitlin Devine built an outdoor installation that lets passersby control the color of her Christmas lights. Read more on Kaitlin’s blog or check out the code on GitHub.

To see the latest UI elements and sample code shared by the community, check out Links & Libraries. You can share your code in the dev category on our community forums.

Highlights & Innovations

Create and control a flow of particles with your hand. Built in TouchDesigner, Simon Burgin’s particle system experiment lets users control the origin point of a stream, pause the flow, and create random interruptions.

Karl Lilje created an Arduino-controlled laser turret, constructed on a 3D-printed mount, with Leap Motion interaction.
