Want a T-Shirt that is going to stand out in a crowd, but can't think of what you want it to say? Consider the simple but stylish (from a nerd perspective, at least) Digital Clock T-Shirt.
The T-Shirt features a soft blue clock display on a black shirt. The unit is powered by 4 AAA batteries, so it may be a bit on the heavy side as far as shirts go, but not bad for a large clock display.
The Digital Clock T-Shirt costs $37.98, and you can find it at The Lighter Side.
