Evolution is definitely the right term for the transformation Tron has gone through. In 1982 the Tron arcade video game was launched to go along with the Tron movie which was released the same year, now 28 years later history is ready to repeat itself with a new game and movie coming this December. I remember the first time I saw the original Tron movie back in 1995 I was blown away despite the fact that it was a 13 year old movie. Visually it was ahead of it's time, Tron in 1982 is the visual equivalent of what Avatar is today.
Below are some screenshots form the upcoming Tron: Evolution game in all it's blue colored glory with a sprinkle of orange of course. Tron: Evolution comes out on December 7 for the PlayStation 3, Xbox 360, PC, PSP, Wii, and DS.
