I've been playing with my IRTC entry from last year (the one that's 
still on the IRTC home page!), with an end to putting a poster of it on 
Zazzle. This will take some time, because I suspect it should be R-rated 
in deference to Zazzle's slightly OTT content guidelines and, as I 
previously mentioned, there is an issue with UK credit cards for age 
validation at the moment.

However, I'm happy with the image itself, so I thought I'd post a 
reduced version here. It differs from the original in several ways. 
Firstly, I've completely changed the lighting. Radiosity is still used, 
but only to deepen the shadows; the light is now cast be two crossed 
area_lights roughly the same size as the ghost. This has the effect of 
making everything much smoother, and does away with the lighting 
artifacts. Secondly, and slightly more trivially, I've added some 
objects in the room to provide a more detailed scene.

My only real issue is the photons used on the glasses and bottles in the 
corner (see detail image). It looks better with than without, but 
doesn't quite look like the ghost is causing them, despite using the 
area_light keyword in the light source's photons block.

Anyway, hope y'all like the images.

Bill
