Based on A. K. Dewdney's column in September's _Scientific
American_, WALLPAP.COM generates amazing patterns on your printer
which are "almost, but not quite, repetitive." Turbo Pascal
source code, documentation, and a program compiled for Z80 (CP/M
or ZCPR) machines are included. Version 3 corrects a bug in
version 2. This is described in WALLPAP3.NEW.
