Here's my entry, the Monitor Mage set. I always wanted a set that had a CRT Monitor for a helmet, but this contest gave me an opportunity to go for a full set.
The set doesn't have any differences per gender at the moment.
Below is some secondary art showing what's possible with the sets...
I just thought this up while looking at this:
The premise is that this item is a early hardmode hammer that is obtained from fishing in the ocean. Looks like a rubber leg from a mannequin, placed on a stick.
47 melee damage
3% critical strike chance
Average speed (30)...
I'm not aware of any wipes of the cloud but Steam has a documentation page of how the Steam Cloud works here. It says that all activity on the cloud was recorded in a text file, so if you have that, the wipe may have been recorded there.
As far as I know the text on the main menu is hard coded. You could probably change the Terraria logo or the backgrounds shown there if you use a PNG to XNB converter, but thats as far as you can go without modding the game.
