Here is what I am supposed to be doing today: artwork, with an emphasis on tiles, as opposed to objects and characters. That's my new Tuesday job.

I decided I hate having to fire up my old computer to do artwork, and short of spending actual money on things, there's only one solution: make a tile editor! It's going to be a fun little project, that should be handy for world builders anyway, and will give me a lot more of the most useful tile-editing utilities than a standard paint program has. And I know trouble with creating tiles has been a very hot topic on the forums as everybody seems to have some problem or another. So this will be good all around.
