It's a pretty well done CGI model, and well animated too. Honestly, it's within the realm of possibility that this actually is a leaked CGI sequence from Trek 11, and if it is, it does two things: First, it wells up hope inside of me that maybe they can manage to make TOS style Trek relevant without desecrating it, but then I recognize that that would mean that they are actually doing in in the TOS era, which I generally regard as an unacceptable gamble with the very soul of Star Trek.
agreed, no matter how good the CGI may be that doesn't change the fact that they are tampering in realms in which they should not play.
