New Work on the 8-dimensional level!

Posted in Building with tags , , , on January 23, 2009 by Wizzy

The latest thing I’ve been obsessing on is a new “rotation” of the E8 Polytope that I built back in September.  The physicist, Garrett Lisi, provided me with the data for a different rotation of the 8-dimensional object.  As a result, the 3-dimensional shadow of that object will have different properties from our previous project.

The 2-dimensional shadow of this new object looks like this:

2-Dimensional E8 Polytope

This object is made up of about 1,000 prims.

The corresponding 3-dimensional object is very intricate and is taking some time to program.  But when it is complete, we will have ventured into some unexplored territory.
