This graphic was rigged together by a friend of mine and me in one sleepless night for a t-shirt. If you would like a t-shirt with this fancy image, make you interest known to me via email, on the other hand the OpenBSD project makes a tshirt with the mad cow on the back.
If you want to see actual pictures of the tshirt being worn, then you can find them at this page.
Initially the subtitle "The Plain Truth" seemed amusing but after people asked me to remove myself form their view, I am sceptical about it.
