Skytyping is a form of skywriting that looks like the work of God's dot-matrix printer. It may not be new, but I've never seen it before and neither had BB reader Eric Eberhardt who noticed an example over LA recently and submitted the link. Eric says, "The neat thing was, you couldn't even see the planes, so it looked like message was writing itself!" From The Skytypers Web site:
The Skytyping process utilizes five airplanes that fly abreast, 250-feet apart and "type" up to 30 character messages in a dot-matrix-like pattern. When Skytyping, the airplanes create messages in the sky that are 5 miles long, as tall as the Empire State Building and can be seen for 15 miles in any direction or nearly 400 square miles.
