I understand that somewhere through the 1930’s a German architect proposed a drawing for a solid object which many deemed impossible, but I have a lovely brass model that invalidates those claims.

The challenge was:

**Given one drawing that represents all three elevations - Create the object!**

Examples: A square is a cube. A circle represents a sphere but a circle crossed with a ' + ' sign might be a beach ball with circles around its 'x,y,z' circumferences; like an orange cut into 8.

**NOW**, this object in question is represented by a circle crossed by an 'X' or multiplication sign.

**MY CHALLENGE**is twofold:

1. What does this object look like? Describe as many of its properties as possible.

2. How might you create it as a demonstration in, say, 2 or 3 minutes? I suggest a firm but pliable medium like children's 'playdough' and a tool like a very simple kitchen utensil would reasonably create an approximation of this solid.
