ThinkGeek’s new interactive t-shirts “includes an interdimensional portal (aka – LCD Panel and camera) that wirelessly connects to another shirt — if you finish your goal, there will be cake.” Video after the break.

The finished product you see here uses two wireless 5.8 GHz video cameras mounted in the front of each shirt along with two high-res LCD TFT screens. The camera in the orange shirt transmits the image to the blue shirt, and vise versa.
