Hmm, I could only find one 32x32 tileset on that page. It looks very nice, though, and appears to use the same format as the one in libtcod like you said. But some of the tiles appear to be DF-specific tiles rather than fonts. I guess this isn't too bad, since most of the ones that matter are still fonts, but it still leaves me wondering if there's a tileset like that that's strictly font only. If one doesn't exist, then that one looks pretty good; thanks!
