I found this little link on the web about a Star Trek Computer RPG game that was supposed to come out a few years ago but never did. Apparently it had voice acting from all the original cast and was supposed ot be SOTA for it’s time… for one reason or another it never got made though…
However there are some snippets of some of the CGI work still floating around.
Here’s one of Spock while they were testing the animation on a talking head
Enjoy. It’s rather funny, it would be funnier if it was actually Nimoy’s voice, but hey you can’t have everything now can you?
