As I approached the nearest tunnel entrance, I heard loud music emanating from below. I recognized the song as "Pour Some Sugar on Me" by Def Leppard, off their Hysteria album (Epic Records, 1987). I reached the edge of the glowing green ring and jumped in. As my avatar plummeted down into the museum, the green vector-graphic theme disappeared and I found myself in high-resolution full-color surroundings. Everything around me looked completely real once again.
