(incf practice-cubes) ?

(tags Rubik's Cube, practice, Common Lisp)

According the article on Nakaji-kun, he has 20 cubes. I don't yet see the reason why you need more than a main cube and one backup. Do cubes have a lifetime? Actually I only have one cube right now, so maybe I should get one more? I recently bought another Speed Cubing Kit (SCK) as a backup. But, I need to readjust the screws and re-lubricate the main cube I got.

I recently subscribed to "THE ART OF RUBIK'S CUBE" blog who mentioned his favorite things about the SCK back in 2007-08. I now know the meaning of otona kai (大人買い) which means buying by the armful. If I want to buy by the armful I can head off to Toys R Us because they've got a sizable bunch in stock. He linked to a nice photo-expose of the SCK by Planet Puzzle (80 pictures). Now I can throw away these plastic boxes.
