Stanimapping is a (possibly) new and embarassingly titled variation on speedmapping. The principle is that you can take as long as you like on a map so long as it's all done in one sitting. One sitting, for the purposes of the excercise is loosely defined as an unbroken spell in your level editor of choice. You can leave the editor to playtest the map, go to the toilet, look at Doomworld or eat lunch but not to sleep, go outside or do, you know, other important real life stuff.
