We made this hi-res air-graffiti light image using a technique we worked out (here). The images are pretty stunning, especially when you see them in high res. Here’s one for your desktop in all it’s glory. Completely free for you to use for any non commercial purposes.
Update: We are uploading full versions of these (gradually) to Flickr. Read the comments for the link

There are many more of these…
So… write some nice comments and we’ll think about releasing the rest in hi-res
