I was at the Hirshhorn (Smithsonian Modern Art Museum) last Sunday to see the
exhibit of Avant-garde Russians, and lo, I saw in the museum shop what could
only be Cubus Albus! I played with it
for awhile (I solved the top 2 tiers before my girlfriend said "That's enough!
You can do that at home!") and it worked more smoothly than my C. Americanus!
So now, I guess, not only is the Cube a source of mathematical inspiration,
but an objet d'art as well.
