I'd like to use some pixel characters as a base for tweaking into characters for my browser-based-game http://ninjawars.net . (In other words, I take a base template and I modify it with colors and pixels slightly to make character variations)
Now, my bbg is mostly ninja oriented, so a ninja avatar to work off of would be great, but more varied character types would be good as well. And I can probably fudge a "ninja" from some other template.
But, err, free-to-use-for-commercial-purposes (e.g. public domain) would be necessary. I'm already makin' a little money off the site from Ads, and would certainly like to make more, so I can't use stuff for "non-commercial use only", unfortunately.
So any source for free-for-commercial-use pixel-y 32-bit-y characters to use as a starting design base?
