"These are pictures taken on November 11, 1999 in the CAVE at NCSA where we were testing out VMD (Visual Molecular Dynamics) the molecular visualization software that I develop at the Beckman Institute. After we all played with VMD for a while, we spontaneously realized that we should be taking pictures of it with Kirby's digital camera since we didn't have any pictures of VMD in the CAVE yet. (we had already been running it for an hour, so the picture taking was the last thing we did.) Once we got tired of playing with VMD, we decided to relax with some CAVE Quake :-)"
