Terraria, anyone?

Just wondering if anyone here has had an experience with playing Terraria, if you do I am curious if it's possible to change the sprite layer of the characters, through hackage. If none of you really know about it, or know what I am talking about, I am more then happy to drop a link down to your satisfaction.

Aye, I play the game, or rather did. I don't know if it's possible to hack it however, it'd would have been smart for its developer to allow modifications but they don't sadly. :/

Truth be told, a few PVP'ers are already hacking in attacks to Terraria. One such attack merely drops 'Egg' images, that when walked into deal 19998 Damage instantly. Maybe it would be possible to hack it, to an extent but then again figuring out how to hack Character Sprites would be difficult.
