Hauntingly cool organ

Not "Twitter" as in "mini-blogging application of dubious value." Check out this video of a "twitter organ." 

I have no idea how it produces noise. It's hard to find anything on the Web about these organs, but here's what Random-Good-Stuff.com says:

"These diminutive music boxes were a cherished ornament in the drawing rooms of ladies in 18th century France and now can have a place in yours too. Simply scroll the punch card through the organ to coax a tune of chirping canaries through the pipes. Did we mention you get to construct it yourself?"

Well, there you go.
