Oh I really like this idea and I'm brainstorming how I can bring it into my art room!

Thank you for this instructable. I needed an abacus for keeping track of stitches while knitting. I didn't have an Altoid's tin, but I used a little box that a necklace came in and it turned out beautifully. I made a Japanese abacus rather than a Chinese one, though.
