A 3D videoprojection screen based on a Dodecahedron dome. I created this for the "Spielplatz" exhibition of photography and video art at Raststätte in Aachen/Germany (raststaette.org).
The projection is done using a simple DLP projector and a hemispheric mirror. Using the hemispheric mirror I'm able to fully project onto the whole dome from the inside with just a single projector. Here is a great video by Michael Kowalczyk of the Projectahedron in action:

In this first version the projected image is severely distorted. I'm planning to measure/calculate a correct mapping function for the system which eliminates the distortions. You will be able to display undistorted images on the faces then.
The Dodecahedron was created using variations of the great OpenSCAD scripts from http://www.thingiverse.com/thing:9359 .
If you want to install or exhibit my Projectahedron anywhere, please feel free to contact me.
