Here's a link for a sneak peek at the 360 degree Hologram that the Alice Cooper Group's co-manager, Joe Greenberg, & Dennis co-ordinated with surrealist maestro, Salvador Dali. Alice wore a diamond Tiara & necklace from Tiffany's and Dali decorated Alice's faux exposed brain, which could be seen from the back of his head, with a chocolate eclair and ants. From above the Hologram, a long arm would reach down into the image and up again. Dennis & Joe had several meetings with Dali, his wife, Gala, & a scientist to make this happen.
