What is "proxomitron"

Proxomitron, the Universal Web Filter, is a filtering web proxy written by Scott R. Lemmon. This program was originally designed to run under Windows 95.

All future development of the program was ceased in 2003 just one year before its author's death on 1 May 2004; even so, Proxomitron is still viable and used on modern Windows platforms such as Vista and Windows 7.
