A free font by Matthew Welch
In downtown Detroit there are a lot of empty, abandoned buildings. On many you can find one or two graffiti turtles spray painted on them. They are usually accompanied by the word "turtle" spelled in a variety of interesting ways: TRTL, Turdl, trdl, etc. I have heard that this is done to the abandoned buildings in protest to the glacial pace at which the city of Detroit is being "revitalized".
The idea for this font came from the "TRTL" lettering in the windows of one such abandoned building. The messages were written one letter per window and said things like "NO WAR" and "NO RACISM" and, of course, "TRTL".
i saw them in a window
