My Galaxies is a website that translates text into images of real galaxies that look like the letters. Fun! Don't like the way it turned out? Just hit the 'Try a new combination of galaxies for the same message' button --- there's more than one 'E' galaxy out there you know! When you're happy with the way it looks, you can save the image in decent resolution for use in a Facebook cover photo or whatever other sadness you have planned. I spelled every dirty word I could think of and some I just made up before I got bored and screencapped the next thing that came to my mind. It was either this or 'penis rocket zoom zoom me to the moon'.
Thanks to Melissa, who agrees it's only a matter of time before we can hire people to actually write things in space with ship-mounted lasers like those guys in the little airplanes do with smoke.
