The 'plushy' effect would do a good job in old dusty rooms of an abandoned hotel in a horror game. Don't know, how fast the shader is to fill a whole room with it, though.
@Superku: I thought I made it quite clear...the presentation even starts with a simple diffuse shading (right one in the pic) to show the difference. But perhaps it simply looked so natural to you that you havenīt recognized itīs awesomeness
@Progger: I could of course, but neither do I feel motivated nor do I have time. =\
