Light Graffiti: the next big trend in photos/art?

I’ve been seeing a fair amount of this getting posted across the web over the past few weeks, and I’m beginning to wonder if it may turn into the next big thing – kind of like what happened with HRD images not too long ago. Check out a flickr photostream (complete with a how-to shot & description) here. Pretty cool stuff. And interestingly implemented – at the moment. Also has interesting possibilities for communication and advertising – but I’ll leave that speculation and discussion for another time.
