A (very simple and short) DOOM shooter like experience (Named GROOM), that isn't using ray casting, but real time path tracing.
Post mortem and gameplay video will be added shortly. I hope that anyone playing it will be able to run it (very good GPU is required!), and hopefully it will be at least a bit fun for him. And yes, programmer's art included!
EDIT: I'm not sure if post mortem should be posted here or not, anyways here it is -
