Scrabble keyboard via Giz. Datamancer writes -

This keyboard was commissioned by a couple of friends of mine from back east (NJ) who are avid Scrabble players. Most of the keys are made from real Scrabble tiles that were all hand-beveled (truly an exercise in patience/masochism!) and built onto a USB, clicky, mechanical-switch keyboard. This keyboard was going into a Mac environment so I decided to use brushed aluminum for the casing and round all of the corners to keep with the sleek, simple Macintosh styling. Near the end of the build, I decided that the keyboard looked a little too minimalist so I added some silver hardware and a seam to put a slightly industrialized twist on the design.
