PolarGeek's IRC Hack (PIRCH) may be quite a mouthful, but the client itself is one of the best IRC clients on the Internet today. PIRCH offers an extremely attractive, graphically-appealing interface to go along with powerful features, an intuitive design, and more than sufficient context-sensitive online help documentation. The only major downside to PIRCH is that its future development is questionable -- the latest version is PIRCH98, which was released back in the middle of 1998.
