New York City has some nice bike's-eye view videos (for a "Virtual Ride" of the new Manhattan waterfront greenway) -- an unbeatable way to show the realities of bikeways. I could see this type of thing being used in Seattle to: 1) communicate with decisionmakers who don't bicycle about bikeways, in a highly visual, dynamic way, and 2) give bicyclists route previewing capabilities for trip and route seleciton and for wayfinding.
