For those who like their clocks to do more than tell time but can’t handle cuckoos or annoying chimes, Chinavasion offers the Time Cube Desk Clock. Triangular sections rotate around a central line to divulge seconds, minutes, and hours. After 12 hours, it begins the process again. At a size 96 x 96 x 96 mm, it uses 1 AA battery. You can order online for a price of $11.82 and, after getting it home, spend the next two days in geometric bliss.
