The most obvious difference between birds and non-avian dinosaurs is the fact that most birds can fly, and as far as we know non-avian dinosaurs couldn't (although it's possible that some very closely related dinosaurs could glide and maybe even achieve powered flight).
Tron was originally manufacturer in 1982 by Bally Midway. The uniquely shaped arcade cabinet features characters and the movie. There are four distinct games per level. Light Cycles: The player controls a Light Cycle that leaves a blue trail. The joystick controls the direction of travel and the trigger controls the speed of the bike.
Nibbler (1982) is a single-player arcade game where the snake fits tightly into a maze, and the gameplay is faster than most snake designs. Another single-player version is part of the 1982 Tron arcade game, themed with light cycles. It created new interest in the snake concept, and many subsequent games borrowed the light cycle theme. Starting in 1991, Nibbles was included with MS-DOS for a period of time as a QBasic sample program.
