Interactive visual installations representing the mathematical constant π, its use from simple colors on the screen to advanced graphics, from natural forms to forces that operate on them.

The visual projections are created using GLSL, VDMX and TouchOSC. Each projection is composed of 3 interactive animated layers - color gradients, shapes/noise and an object from nature.
The code of each layer was modified by extracting parameters that influence different equations and interactive versions were created using ISF, that could be blended and projected via VDMX.
The user interface for iPad app was created in TouchOSC. Driving visuals via iPad significantly improved the interaction experience compared to the earlier prototypes that used game controllers instead.
Using the iPad, users can manipulate projections inside a 12-foot geodesic dome (made out of cardboard) to change depth, scale and colors. The visuals are spherically projected inside the dome using 2 short throw projectors and Matrox TripleHead2Go with carefully curated sounds as accompaniment.
