It has been a few days since I've updated because my hard drive and operating system has been reinstalled, but I'm back to contributing. Benjamin Hurdle's Paper Pipe Organ actually plays music when constructed! You can even write your own songs for it to play. This model can be bought from Marcle Models in Britain. If you are curious as to how a paper model can play music, read the explanation of Pneumatic Drives and Paper Mechanics on Walter Ruffler's site.
