Stunning animation rendered with Octane Render

Just saw this very impressive video on the Octane forum today and thought it deserved its own post (the level of realism is otherworldly):

The whole scene is 3D. Rendertime was two minutes per frame on average on a single GTX480, so eight of these GPUs rendering simultaneously would reduce the rendertime to just 15 seconds per frame (rendertimes in Octane scale almost linearly with the number of GPUs), which is just completely nuts considering the quality.

Update: there's a new video on youtube showing that Octane can produce a real-time rendered low resolution preview animation of an outdoor scene with a rendertime of only 55 milliseconds per frame!
