Greetings, fellow art afficionados.  :)

I've been working over the last couple of days on the beginnings of an OpenGameArt.org Community Tileset (note the image attached).  It's just grass and dirt at the moment, but I think it's a good starting point.

At any rate, my ultimate goal here is to involve the community at large in the creation of these tiles.  The plan right now is to dual license it, under the GPL, plus some yet-unnamed license that will allow non-GPL projects to make use of it in exchange for a contribution of content, thus growing the art pack.  If you'd be interested in contributing, stop by our IRC channel (available via FreeNode's web chat) and say hi.

Peace,

Bart
