Well, here's what I've come up with so far. Might do a few more later, tell me what you think of these though.

Or a bordered one, if you prefer.

Good luck all those who are entering!

*edit*

I made some more, simpler ones.

People around here seem to like borders, so that's why there are some bordered ones.

Heh, just noticed that I apparently like grids. I don't usually use grids in things, but I may have to change that in future…
