Reach, Color, Repeat 2017   
Reach, Color, Repeat is an interactive video installation that allows visitors to create a digital abstract painting by using body gestures.
Dimensions: 2.8 ft x 3.3 ft
Materials: computer with custom software, Kinect v2 interface, video projector
As a visitor approaches, she sees her shape on the projected screen with a palette of colors overhead. More than one person can reach up, select colors, and use their hands and body movements to draw in the air. The system captures the gestures and patterns of colors created, and starts a watercolor simulation that causes the colors to bleed together. Painting strokes that were captured are added back into the composition, randomly rotated and scaled. This is repeated until a unique, colorful abstract painting is complete.

A Microsoft Kinect is used to capture the visitors’ gestures, which is connected to a laptop with custom software. A video projector provides the imagery for the screen.

This installation involves the viewer in a satisfying process of interacting with vibrant colors to experience the creation of a work of art.

Several open source software projects were used in this installation:
OpenFrameworks - an open-source C++ library for creative coding
ofxKinectV2 - Joshua Noble's addon for using the Microsoft Kinect V2
ofxFX - addon for that make easy to use GLSL Shaders by Patricio Gonzalez Vivo

I would like to thank Jennifer Lim for her help with this installation.
