This is quite possibly the coolest, gadget-like thing that I’ve seen on a t-shirt since, well, yesterday’s Tee. The image to the left is an example of the new photochromic ink shirts from I-Manifest. What’s photochromic ink? To shorten the Wikipedia entry, photochromic ink only shows up in sunlight (or other UV sources). So in this design, the plants only ‘grow’ while outside.

Now far be it for me that geeks are a shut-in group for whom this shirt’s duplicitous nature will be lost on. However, if you do spend the $32 it takes to grab this tee for your very own do try and get something more than a screen tan, will ya?
