The site goes by the fanciful name of donjon.
My favourite random generators are:
- the Random Dungeon Generator – Old School at its best
- the Random Treasure Generator (to populate your randomly generated dungeons)
- the Random Weather Generator (whoa)
- the Weird Random Generator – 'cause it's weird
- the Star Wars D6 System Generator (whoa)
You're gonna spend hours and hours poring over all the generators, you're gonna hate me :)
