This Revolights project has already met its goal so you can read through the proposal without a feeling of guilt for not monetarily contributing. The basic idea is to provide smarter lighting for bikes through a rather clever (and simple to install) device that is being developed. The video demonstrates the beta device about 1:40 in - go take a peek. The lights look, and function, great while in motion but look a little awkward when stopped. Regardless, now that funding has been achieved it would be cool to see these out and about.
