The Atmark Mug from the Art Lebedev Design Studio comes in 5 cool colors (red, orange, blue, green and black). As I am writing this, it looks like red is sold-out, but check back with Art Lebedev and they should get it back in stock soon.
In case you’re wondering, the name of the mug, Atmark, comes from the @ shaped handle. Pretty smart. Very cool.
