A beautiful DX11 demo for your gaming PC, made by a Japanese company called "Sakura" I think..
The rendering capabilities of this demo are amazing, looks so realistic, you will need a DX11 card though, and a good one at that!
I uploaded it to Moddb because the original site is in Japanese.
Controls, as they are not mentioned with the demo:
ESC - Exit
S - Screen Capture
PAGE_DOWN, PAGE_UP or M1+M2 - Zoom
HOME, END - Increase/Decrease DOF
MOUSE - Drag Objects
INSERT, DELETE - Increase/Decrease DOF
SPACE - Reset
ENTER - Next Scene
