With a lot of people learning a Greek letter they didn't know about right now, I am reminded of a device I had to use in school called Omnicrom.

If you remember rub-on dry transfer lettering, this was able to make it. We were required to use it to create package mock-ups. You'd take the untreated sheets of color (which could only be bought from the department office at a specific half-hour once a week), run them through the machine with film negatives of the designs (ordered from a repro shop with a four-day turnaround at our own expense), and then dip the sheet in stinky chemicals to carefully wash the rest off. Then you'd rub it onto the fancy paper or whatever, and half the time it wouldn't work because that particular color cooked on too hard.

Just one of many antiquated practices they taught us before turning us loose in 1993 on a world exclusively looking for people to program websites.
