Megatripolis was an underground London club-night created by Encyclopaedia Psychedelica/Evolution editor and founder of the Zippie movement Fraser Clark,[1] partner Sionaidh Craigen,[2] as well as a great many others.[3] The club combined New Age ideology with Rave culture to create a vibrant, festival-like atmosphere presenting a wide variety of cross-cultural ideas and experiences. Club nights ran regularly on Thursdays from 1992 until 1995, being the focus of much of the Zippie movement. The club and its related activities such as the Sunday club for mothers and children and those interested in a more relaxed sharing of support, also helped to popularise ideas such as cyberculture and the Internet between those years.
