4. A Set of Bagpipes

What better way to pay tribute to Scotland's musical heritage than with a day-glo set of plastic bagpipes? Made with real goat skin, the wheezing whinge-sack could be used to give a brand new slant on hits like Purple Haze's Smoke On The Water and Jimi Hendrix's Voodoo Child. Alright, so it would sound terrible, but it would give you a brilliant way to piss off your neighbours in the middle of the night. It also gives all you sexually-insecure guys out there an excuse to wear a skirt - go on, you know you want to!

3. A Triangle

Harmonix actually wanted to include a triangle with the original Rock Band, but at the time it was just too difficult to fit the required technology into a hand-held accessory. However, the ongoing march of technology means that such a device may be possible by the time Rock Band 3 is developed. On the basis of the early prototype we've seen, the Triangle will require the use of 18 AA-size batteries, six of which will fit into the small wand used to beat the instrument. Unfortunately this cumbersome power supply makes the peripheral extremely heavy, so it's likely that two players will need to work together if the instrument is to be used properly.
