Math teacher Willy Felton (featured here before), has done it again. One of my Projects of the Month last year showed how to make a geodesic dome:
Willy used this model is a basis for a 5-day geometry project. Not only did students make the domes themselves, but they had to use them creatively in a larger model.
Here's a video of the class's best models (my favorite is the Zombie Defense Compound):
I was wondering about the fireball-looking models used in one of the scenes (Superman vs comets), and those came from the 3D Warehouse, from a search for "explosion." It's a very neat model which will probably one of next month's projects.
Anyone can design anything in 3D! http://www.3dvinci.net/
