It's a multi generational project being carried out by the Roddenberry estate alongside OTOY and Trek alumni such as Denise and Mike Okuda and Doug Drexler. The idea is to collate and preserve significant aspects of Gene's work and present them in an innovative and interactive manner for both fans and as a reference for future Trek productions.
So far they have a number of virtual bridges, interviews with cast and crew as well as some additional scenes for the Cage and Generations they have shot with a lot more material to come.
