The LHArc/LHA archiver is a multi platform archiver made by Haruyasu Yoshizaki, which has a relatively good compression. It uses more or less the same technology like the ZIP programs by Phil Katz. There was a hack named "ICE", which had only the graphic characters displayed on decompression changed.
