The BeebSID allows you to attach a Commodore SID audio chip to a Acorn BBC computer. The case was inspired by the Internet box used in the fantastic British sitcom, IT Crowd.
I have uploaded a video to YouTube to show the device in action. Enjoy!

I just wish there was an actual SID device, say USB-based, that worked with Mac OS X. (There seems not to be.)
