Natalia Galin created an interactive art installation that inverts the usual concept of shadows being cast as black silhouettes during the day and turns them into a blaze of color at night, mirroring the movements of people passing by.

Shadow Wall is a 180 x 120 LED display for Sydney’s Vivid Festival of Light.

Natalia and team ported the code to Python in order to access the full suite of Open CV functionality.  They also sped up the serial data transfer.  Their code can be found on GitHub.
