GLTerminal

GLTerminal emulates a 1970′s terminal monitor, complete with flaws in brightness, warped display curvature, and flicker.

It even simulates baud rate lag. And! for extra verisimilitude, the character colors can be green or amber. It’s basically just a Terminal replacement that uses GL to create the appearance of an oldschool terminal, complete with monitor curvature and all. Everything else works as it should, so if you’re looking for a fullscreen old school alternative for Termianl, or just want something fun to work in for a while, try out GLTerminal.
