Cell phone keytar
From the crazy-weird file, Steffest from Belgium has created a DIY cell-phone-keytar monstrosity. The Phone Guitar was born out of a presentation about mobile cross development that Steffest was working on.

He says:
Music apps are a really cool type of mobile application, they let you you unleash your musical creativity wherever you are and are perfect to jot down a quick idea or to jam along. For years one of my favorite pastimes on the train was to do some retro musictracking with the brilliant Milkytracker, but this time I needed something more. It turned out to be somewhat geeky…even for my standards
The ‘instrument’ uses apps on 3 mobile platforms: Android, Windows Mobile and iPhone OS. All the phones are taped together onto a piece of wood, along with a battery powered speaker. The Pocket Stombox app is used for the effects, and the guitar is played on iShred.
As a developer I didn’t quite succeed: audio latency is a b*tch and building the app from the same source proved to be possible but unusable, so I ended up writing it three times: in java for android, in C# for windows mobile and in Objective-C for iPhone. More on that later, but boy did I have fun playing with it.
In screenshots, the setup looks like this:

And the moment you’ve all been waiting for:
Who said iPhone OS, Android and Windows Mobile don’t play well together?
