Some pretty extreme methods for waking up are out there, but for those of you who'd prefer something a bit more natural, have a passing glance at Philips' Wake-up Light. This admittedly brilliant device simulates the rising of the sun by gradually getting brighter as your
desired required wake-up time draws near. If that's not enough, your windowless apartment can become the middle of Central Park with the inclusion of bird sounds, babbling brooks and millions of citizens yapping on mobiles. Okay, so maybe that last bit will come with a future firmware update, but if the current iteration is good enough for you, it can be acquired now for around $120.
Update: Seems this has been around for at least a bit in some parts of Europe. Share the love!
