KenD -- Ken Dickey has used too many programming languages on too many computers for too many years to remember, but he still prefers Scheme.
Recently Ken gave a talk at the Victoria Scheme Workshop about a simple "design sketch" GUI which currently works with Chez, Gambit, Ikarus, Larceny, PLT, and Ypsilon Schemes.
Ken now lives on an island off the coast of Washington State in North America. He can be reached via email: Ken [dot] Dickey [at] Whidbey [dot] com.
