I should probably point out that this particular post is entirely referral-based thanks to this post on TIGSource.

Additionally, that astonishingly handsome and intelligent indie games website tigsource.com have also pointed out that RPS-favoured fantasy-management ASCII project Dwarf Fortress has had an unofficial graphics update thanks to the work of Mike Mayday over at RPGCodex, who has compiled various tilesets. Good work, Mike.
