OwenShow is an open-source file browser demonstrating various techniques/failures in Borland Kylix/Delphi code, including fork, drop/drag, and much more. Unlike other browers, directories are scanned explicitly and, if desired, to full depth, i.e. to get detailed descriptions of directory trees. Finding directories/files is supported by inexact/exact cumulative search.
Quarters is a strategy game for two players. Although its rules are relatively simple, it still offers some of the same opportunities for skill as in chess. This program was originally conceived in the summer of 1986 during a study of the mini-max algorithm for chess playing computers, and was thus designed to offer some of the same type of strategies. The game was originally written in BASIC, then ported to Turbo Pascal, then to C, and finally to Java. The Java version is not necessarily object oriented, since it is a crude port from the C version.
