About
glpong is an open-source reimplementation of Pong using OpenGL and SDL for Linux, licensed under the GPL. It's a single-player game against a computer-controlled opponent, with the near paddle controlled by the player and the far paddle controlled by the machine.
Getting started
Build it with the standard `./configure && make install` process, then play using the left and right arrow keys to move your paddle; F10 captures a screenshot, and Escape exits the game. Running it with any command-line argument switches it to fullscreen.
