The guy who created the tower of pennies to the right has WAY too much idle time on his hands...check out the other free standing penny creations he has made using absolutely no adhesives - they are held together simply by their weight. He has more patience and steadier hands than I have, that's for sure!

Oshiro is beautifully imagined Japanese-themed update to the old Tower of Hanoi game. Beware though, it is addictive and maddening...I'm currently on Episode 2, Scene 7 and just can't seem to figure it out. Maybe when I get back home later...
