Anyway, you could use it's current actively developing recipient - OpenCobalt or still download the old Croquet distribution from here
Ok, I'll try to be clear as possible.
Infra red blocking filter is removed from the camera to [enable] infra-red vision. It is needed, as the projector and camera should work in different light's diapasons. Camera inside the table looks/points to the same table's surface, that projector illuminates.Thus camera shouldn't view the visible light, but just infrared for recognizing the printed markers.
Yes, PS3 eye camera is generally used as it has ~60 fps and thus is very responsive.

Hi Nikolay,
Thank you for your quick reply. I was at your website yesterday and downloaded the Krestianstvo SDK, the Croquet site seems to be down so could not down load it but I got seaside and some others smalltalk kits.

Right now I am downloading the reactivision at sourceforge.net but I am a bit confused on the camera side of things.
Do I need infra-red or not for the project? The NUI group guideline says to remove infra red filter from the camera but did not point out the reason for this. My question is --> Is the removal of the filter from the camera allows [enable] infra-red or does it remove [disabled] infra red? Please explain! I asked this as I have some infra-red web camera that I bought from Ebay sometimes ago but it is important to be clear. Many thanks!

I must admit that the NUI group website is a very well established knowledge-base portal. I downloaded loads of information and packages from the site and I am going back there. I already have two projectors at home that I used for teaching and some laptops. I just need to go to pound-land or Art shop in my area to get plexi-glass and a tall box from local stores to start experimenting things. I will look on Ebay today for Sony PS3 eye camera. Once again many thanks!
