This is case for the Raspberry Pi plus the Adafruit LCD+Keypad Pi Plate (http://www.adafruit.com/products/1115). It comfortably holds and protects both while leaving all the port accessible. Most importantly, it snaps onto a bracelet that allows you to strap your raspberry pi to your wrist!
I used this for my "Control My Cap" Project, wherein a web-connected Raspberry Pi on my wrist was used to control a light-up display on my graduation mortar board. You can learn more here: http://www.jeremyblum.com/portfolio/control-my-cap/
Print out the top and bottom parts of the Pi case, as well as the bracelet. The bracelet will need to be printed with support. Install the pi in the bottom of the case, and mount the LCD plate on top. Snap the top of the case on. Then, snap the bracelet in to the bottom clips. I recommend securing it with a few dabs of super glue since the fit is not very tight. The channel on the bottom can be used for routing the power micro USB cable so it can run up your arm along with the other USB cables that you might choose to plug in.
