Christian Wirth (a.k.a. RaD Man) is founder and president of ANSI Creators in Demand, now simply known as ACiD (www.acid.org). This art group has run for over 14 years with regular releases of artpacks, BBS
mods and software products, including ACiDDraw and ACiD View for Windows. Now in "retirement", Christian directs his energy in new ways; organizing the Pilgrimage USA demoparty, hosting scene talk show The ARTS, and speaking at conferences around the world on the interesting history and subculture that surrounds this ever creative artscene.
Recently, he finished work on a DVD-ROM featuring over a decade and a half of artpacks by ACiD and many others called Dark Domain (2004), available at http://www.darkdomain.org/.
