Squeal/Singing Face, an interactive portrait. The portrait "sings" when you tap certain part of the face, tilting the device will alter the pitch and make it possible to perform music. I updated Moving Mao from square pixels to Delaunay Triangulation for better definition of the face detail and more realistic facial movements. I used Openframeworks and OfxDelaunay library to create Squeal. This work is currently in development, although Delaunay Triangulation is a common technique, using upon portraits was a well-established style developed by Jonathan Puckey. To avoid association to his works, further exploration in the rendering style, and interactive functions is needed to make this work more unique.
