Ghostscript (well, gv) got me through the 1990s and beyond as part of my TeX -> dvips -> gv workflow.

Kudos and thank you to those who maintain it and the associated packages!

Yep, and I remember the moment of surprise and delight when I once included an eps file into my TeX output with some color and saw the color show up in my gv output.
