I've attached a ball to the rolling ball sculpture with the idea that you cut it off and sand it and it should work as the marble. The marble is 5...

The answer to the burning question, what would the sculpture Ora be like if it were a hypercube instead of a cube? A bigger one is here.

Double D6This is a compound of a nearly regular D6 and of a sum-D6. As the sum-D6 that composes the shell gives results from 0 to 5, the core is nu...
