Heres my entry for the DX11 contest. Its an implementation of realtime radiosity using voxel cone tracing.
I'm kinda disappointed because I spent over a week making art for an environment, which was supposed to be the main part of the entry, but about 12 hours before the contest was over I realized I wasn't going to have enough time to finish the environment so I used the Sponza scene instead. So I only spent about 3 days on what actually got submitted .
Heres a video:
And some screenshots:
