More fun with the Raspberry Pi

Congrats to the Raspberry Pi, the little device that just keeps going and going. They've sold 3 million units so far and the demand shows no sign of slowing. And the creative new uses for it keep on coming:

• DIYer studio CowFish created an awesome little gadget that hacks his car's OBD ("on board diagnostics") data port to read real-time automotive data and display it on a screen while driving: turns out it was a pretty simple hack.
• Andy Felong mixed a Raspberry Pi, an Ipad, and a vintage 1942 radio to create ... an improved 1942 radio.
• Better still, Lon Steidman has used a Raspberry Pi to create and run a telnet Bulletin Board System (BBS) on (get this!) an Apple IIe!

Have a look at Her Majesty the Queen of England in that first link: she's gazing thoughtfully at a couple of Raspbis and some assorted hardware. What gadget do you think she'd build?
[Ed note: The steady stream of cool projects being built around Raspberry Pis is fascinating and captivating. Wish this damned day job didn't keep getting in my way of having all this fun.]
