there use to be a journal, i cant remember if it was just a clear arclyric(sp?) case or cubed, i dont remember but now im looking to read up on it again, i think it will be my next project, not to really copy just to brush some idea's to spin off of.

There is one on thinkgeek.com but it is 200.00 w/o shipping.

i'd go to the hardware store and buy some 1/4" plexi and build my own cube case for about $50usd.
