To the outside world, the t-shirt is just an ordinary blue top with a nice graphic on it. However, a tiny camera is situated on the chest; it connects up to a feedback remote (best hidden in your pocket), allowing you to take up to 150 pictures on the sly.
You take photos by pressing down the remote, which then vibrates once it has finished taking the picture. And you can transfer the photos you take to your computer (Mac, Windows, or Linux) via USB.
Although ThinkGeek makes no mention of the camera’s exact specifications, the Website does mention that the camera shouldn’t be used in the dark, unless you want either blurry objects or pictures that hardly come out at all. It takes 640 by 480 resolution photos, which isn’t so bad for such a small item–that’s enough detail to email everyone at your workplace the culprit eating all the office cookies.
