Morning /wg/

Been meaning to post this for a while. I've got several computers all running synergy. I'm looking for a wp I can chop up and spread across all... or a high res pic that I can shop into an awesome wp set... or a good set of wp's that would look nice spread across all. Or should I just make something from scratch (Got shop skills enough to handle it)? Any suggestions?

Anything larger, I can work with.
