Sure, anyone can
set their terminal font to green on black and feel l33t but if you really want to go old-school you need GLTerminal. It's a full-screen terminal app for OS X that will make
your screen look like an old 1970s tube monitor "complete with flaws in brightness, warped display curvature, and
flicker." It also simulates screen lag and you can choose green or amber text. Though it really does work,
GLTerminal is "slighly broken," not open source, and abandonware, but industrious hackers are working as we
speak to smooth out some of the kinks.[Via Boing Boing]
