Just say that the conspiracy theorists are correct and the crosshairs really were behind the objects - what does that mean exactly? Either one of two things:
1) The crosshairs are on the camera lens - therefore the flag and equipment that is supposedly in front of them must be teeny weeny little models inside the camera...
OR
2) If the crosshairs are not on the lens then they must be huge 20ft-high objects sticking out of the "lunar" surface like grave headstones. Now if I wanted to fake a moon landing, I wouldnt place huge alien-looking black headstones in the background of the photos...
Yeah, technically it's an edited screenshot rather than a 3D render, but it's pretty good nonetheless. The perspective and shadows match pretty well. Nice job.
It's about £26-£27 when VAT is added. It's not available a week earler in the UK, the Orange Box is released to everyone on October the 10th. Plus, if you already have HL2 and HL2:Ep1 you will be able to give them away to a friend.
AND you get Peggle Extreme too. A 10-level puzzle game based on the Orange Box games.
