I agree with Jamie Zawinski, who says writing anything in postscript is "totally out of control." 😝

What would a bar owner know about programming ?

All that aside, you should look into Postscript. It's actually a complete language, pretty interesting. You can do a lot of stuff with it, I think there's even a website dedicated to postscript programming, with lots of examples. It's not just for printers.
