Following Emily's reminder that this year's Interactive Fiction Competition entries are now playable I started to browse and found a curious and enjoyable piece called 500 Apocalypses [entry page] by Phantom Williams. It's a fictional in-browser museum/garden curating the apocalypses of various societies as translated from an extraterrestrial resource. There's also a cool FAQ which augments the experience nicely, toying with the fact/fiction distinction.
