Siri has been something if a disappointment so far—more flash than substance—but this particular trick is a mighty impressive novelty. A neat new hack lets Siri play music on a Yamaha Disklavier player piano from music files in your library.
The hack, developed specifically by and for Yamaha, works by streaming a special MIDI version of the music file through an Apple Airport Express and into the Disklavier piano, which then reproduces the piece, complete with key and pedal impressions. And typical to Siri, there are some Easter Eggs jammed in there, like being able to tell your iPhone, "You played it for her, you can play it for me. Play it again, Siri," and it will launch into "As Time Gies By" from Casablanca.
It's a very cool hack/feature, though close to £10k is maybe a little much to make your iPhone feel better about itself. [Wired]
