Create your desktop wallpaper at 1024 x 768, 72dpi
Name your entries in the following format to help us add them on-line faster: dc-11-[your-handle]-[#].[jpg] where [your-handle] is your handle in lowercase with spaces replaced with dashes. [#] is replaced by a number representing the current logo you are submitting. [jpg/psd] is a jpeg or an unflattened native photoshop file, the two file formats accepted. For example, Net Ninja is submitting three jpeg logos. He would name the first one dc-11-net-ninja-1.jpg and the last one dc-11-net-ninja-3.jpg.

Submissions will be added on-line to the DEF CON web site, and cool wallpapers will be printed in the con program.
