About: The Nth Degree (Star Trek: The Next Generation)

"The Nth Degree" is the 93rd episode of the American science fiction television series Star Trek: The Next Generation, and the 19th episode of the fourth season. Set in the 24th century, the series follows the adventures of the Starfleet crew of the Federation starship Enterprise-D. Rob Legato directed and oversaw visual effects for the episode. Legato eventually opted to create a 3-D effect wherein the Cytherian's huge head would appear to pop out of the screen. That, in turn, would allow him to have a literal face-to-face conversation with Picard.
