Call it a wild coincidence, but things like this have probably got a lot to do with the Siemens Mobile group potentially being up for auction. There's nothing that inspires confidence in your team quite like farming out the inspiration for your products to dodgy students in the form of the "Siemens Design Challenge." The contest yielded some hilarious highlights, such a cellphone shaped like a small mammal and another that's operated while wearing it like a mask. Finally, the winning design (pictured at the right) does show some promise (remind you of anything?), though Bluetooth headsets make holding a hand to our heads seem a bit silly.
