Inspiration

• Get an MRI scan of yourself. Process data into 3D models for your favorite organs (brain, heart, liver, etc.) Have a CNC shop turn the model into reality (plastic, aluminum, etc.) The two hemispheres of your brain would make for nice bookends.
• Find modelling software for which source code is available (i.e. SCED.) Adapt it so that it generates Mental Ray files.
• Again, find modeling software, and extend it to accept all the functionality of the geolib.
• Write a collection of interesting shaders and create a website to share them with the world.
• Create some extension of the random-dot stereogram idea. Add color, add animation. Something.
• Port the geolib (as applicable) to the Java 3D api.
