There are many wonders in 276 responses to the challenge 'Show me your homemade instruments'. My favourite is this chap whose Dad bolted together a Vox Continental and a guitar, but there's a lot more: Sxip Shirey plays bowls with marbles, terrifying grinding car guitar thing, strange tiny bass guitar, a circuit bent Buddha Machine, a beautiful-looking touchpad-based homemade synth and this bonkers disc reverb box. There's a lot more - leave links to goodness in the comments. (Thanks, Gareth)
