With yesterday's developer seed of the rumored OS X Snow Leopard "Golden Master" (Build 10A432), users with access to the latest version have been examining it for changes. Among the most obvious modifications, as noted by Gear Live, is a change in the install icon from Leopard's "galaxy" image to one portraying a snow leopard. The change likely reveals the art to be included on the physical installation media.
