  The recent discoveries of giant planets around nearby stars have galvanized
the planetary science community, astronomers, and the public at large. Since
{\it direct} detection is now feasible, and is suggested by the recent
acquisition of Gl229 B, it is crucial for the future of extrasolar planet
searches that the fluxes, evolution, and physical structure of objects from
Saturn's mass to 15 Juipter masses be theoretically investigated. We discuss
our first attempts to explore the characteristics of extrasolar giant planets
(EGPs), in aid of both NASA's and ESA's recent plans to search for such planets
around nearby stars.
