“RTHDRIBL is an application which is so awesome, it needed to have its awesomeness reduced by giving it a retarded name!” The name is an acronym for Real-Time High Dynamic Range Image-Based Lighting. You can download it

That’s all in real-time: motion blur, depth of field, reflection, refraction, and lots of other fancy effects! Official website: http://www.daionet.gr.jp/~masa/rthdribl/

It’s old (2003), but that doesn’t reduce it’s awesomeness.
