Gadget design concept gallery: Tokyoflash Bluetooth necklaces

Tokyoflash, the Japanese destination for cool and borderline incomprehensible watches, recently asked designers to come up with renderings of Bluetooth necklaces. Ranging from dog tag-inspired chains to chocolate-shaped squares, the results are pretty interesting.

But what is a Bluetooth necklace, and why would you ever want one? Fair question; the gadget would serve as a controller for a Bluetooth-enabled phone or music player, with playback controls as well as indicators to alert you when you get a call. Without a microphone or earpiece it's not exactly the most useful product, but there's no question they look damn cool.

Check out all the designs in the gallery below.
