So, whatever happened to Duality? (Off-Topic)

There's this thread about it on MBO (particularly this post).

Also here's a gallery (also via MBO) with concept art and level designs from Courtney Evans' Flickr (did the Tempus Irae Marathon scenario). There's also a few pages with screenshots and music on his website, but you'll have to Google/Bing/DuckDuckGo for that (or just check this thread on MBO).

There's hopefully more stuff out there about it, somewhere. But, those are just what I have bookmarked from one night a year or so ago (boredom + craziness + also wanting to know more about it).
