Produces an amazing array of info about a map (or a folder full of maps), including all basic stats (polys, floor space, weapons availability, textureset, etc), and some aggregate stats on multiple level maps. It was inspired by MapInfo, but generates much more information. This update is a complete overhaul. There are statistics on new things (including textures, lights, liquids, and sounds), and special value statistics, and the source is completely Loren's (all of Kirill Levchenko's code has been replaced). Source is included.

The closest anyone's ever come to a cutscene level. Pretty astounding, even given the limitations... play it to see what it's all about. (It's cool. Really cool.)

Hastur's Workshop, at Double Aught's site, has long been a source of inspiration and answers for marathon mapmakers intent on a better product. Michael Watson decided to preserve those pages in an offline form, in case they are ever removed from Double Aught's pages.

5 maps, ranging from small and simple to large and starting to be complex. They don't feel complete, somehow... lighting and sound is haphazardly implemented, for example.
