One of the ILM animation guys -- I think it may be the Takahashi guy who did DEATH BECOMES HER and later moved to Australia to work at WETA -- who animated that little guy, and he has no detail at all, so he really isn't anybody in particular. I think it may have been just a silhouette animated. They pin-blocked the animation so that it would stay in registration with the lil window, which was pretty fancy-ass stuff back then (they won an oscar for doing some of that in INNERSPACE the same year), and almost unheard of for TV work in that era. I think that might be one of the rare bits that was comped at ILM rather than at the SoCal places that finished off and recomped the ILM FARPOINT ship elements ... it just doesn't have much of that video-ish look I associate with most early TNG shots.
