DZ should have an archive of all the logos for every SELEM shirt going back to the very first SELEM in 2007. The first design was mostly text, with a laser line and beam burst graphic below the text.
The designs that Shadow has submitted look really good! Unless someone else has any last-minute submissions, I'm going to declare him the winner for the logo design again this year.
I need to check with the shirt folks to see about the viability of a few things, but I've already narrowed it down to one of the last three designs posted in his thread above. (Just need to make sure that there won't be any issues with the embroidery.)
