I'm thinking of getting a screen from www.drhscreens.co.uk 

I can't view all of those images for some reasons Latte, but the first two I can see and that looks absolutely stunning, particularly given it's a photo of the projection. It must be pretty immersive when the screens are that big, right?! Out of interest, what is it you're using Mr. Latte?
Do the majority of projectors do 1:1 mapping? I'm building a new PC in the near year and if I could struggle to a 1080p projector as well (say they did come down to a more reasonable £1500 or less) then I could game on it with my PC as well as Xbox. Stick a Blu-ray drive in it and I'd be covered from all HD angles.
Also - I had a look at the Goo stuff, and it's about $250 - no UK suppliers by the looks of it - and for that amount of money I think I'd rather buy something that I couldn't completely **** up.![]()
