This project is pretty cool. Normally having a big LED array is challenging enough to get working properly considering how much power it can draw. Making it flexible adds another layer of complexity but the payoff is worth it considering all of the novel applications it opens up. One such application this project has been used in is a Major League Soccer match.
This LED array was placed under a players jersey and displayed information like the current score and other match statistics. This was an exhibition match, but shows off but one interesting application if you can make the state of the art more amenable to the softness of our bodies and the garments surrounding them.
There has got to be loads of other cool stuff that can only be done (or made easier) with flexible LED panels. Have you considered wrapping the entire light post in your front yard with something like this rather than just having one bulb on the top? What about gathering multiple flexible displays to replicate Megascroller Mario? If you have a project that uses one or just have something in mind you would use one for , tweet us at @tindie
