Christian Wirth (born in the 1970s), better known by the pseudonym RaD Man, is an American computer artist and historian.
He works in the field of ANSI art, a method of creating art using a limited set of text characters and color escape codes based loosely on the relevant ANSI standard (X3.64: Control Sequences for Video Terminals and Peripherals).
By 1992, the increasing file size made this process impractical, and this led to the development of the artpack, where groups of artists (including ACiD) would upload monthly update packages instead.
[4][5][6][7] Since 2002, RaD Man has worked as a historian and spokesperson for the artscene, collecting information and interviews with the artists involved, and creating reports and presentations on the lineage of computer art.
Some of this work includes The ARTS, a talk radio show which discusses the many different facets of the creative computer underground scenes [8] and the Pilgrimage 2004 demoparty.
