I think he's called Lindsay Pollock from memory, has a web site somewhere, has a wide range of instruments that he has been taking to public events in Oz for years. He's been all around the world too.

He a sopemthing called a "thongophone" - tuned lengths of 4" PVC pipe, and you slap the open ends of the pipes with a rubber thong. Lovely deep (some of the pipes are more than 8 ft long) resonat sound.
