A Belkin Nostromo n52 gaming pad thingy - weird gizmo with 15 keys, a scroll wheel, and a mini joypad. I think it's designed for left hand use, with the mouse operated by the right hand, but while it seems to work correctly I can't think of any reason I'd want to use it, so another one to go to eBay. Got it for £2.50 anyway.
Fingers crossed for nice weather tomorrow, there's a good car boot sale in Kilburn.
