This project implements an interactive plant using L-systems in TouchDesigner. The L-systems are controlled in real-time using a Leap Motion controller. Currently, the control is very simple. As the user raises their hand, the plants will grow with it. As they grab and hold their fist, the flowers will blossom. In order to make the system performant, it is implemented using geometry instancing instead of L-system's default stamping mechanism.

Here's a video of how the plant is controlled using Leap Motion.
