A dozen years ago, I had this idea: a clear plastic enclosure and mounting brackets for your car so you could change bumper stickers whenever you wanted, and not end up wallpapering your trunk with all the important things you want to express. Yeah, I never went anywhere with that. But when an email about Talelight showed up in my inbox, I was immediately excited. The digital age had finally caught up with bumper stickers!

It makes sense, of course, that display technology has advanced to the point where this could work. And it’s not to say that other folks haven’t tried similar ideas in the past–like big fat LED screens mounted in rear windows. But the folks at Talelight really seem to have taken the idea, and the safety concerns, seriously.
