==Caption for Radiosity_Progress.jpg== 
 Sorry Trevor, I have reverted the caption for Radiosity_Progress.jpg. From "As additional bounces are calculated in shooting radiosity the scene becomes progressively brighter." back to "As the algorithm iterates, light can be seen to flow into the scene, as multiple bounces are computed." 

 This is because I believe the original caption to be the more correct one. This image was not rendered using shooting radiosity. It was rendered using texture mapping radiosity. Secondly, the image is not simply getting quantatively brighter. Rather a qualitative change is happening: light flowing through the scene.
