Panther tank
Panther, a battle tank-driving simulation named after the Panther tank, was one of a handful of early first-person computer games developed by John Edo Haefeli and Nelson Bridwell in 1975 at Northwestern University. The game was developed for the multi-user interactive computer-based education PLATO system and programmed in the TUTOR programming language and utilized scalable vector graphics called linesets. A 1977 development of Panther, with more refined graphics, was named Panzer, the German word for armour and tank.
