Postscript is actually really easy. The language itself is RPN based (like the older HP calculators) and really fun to work with. Grab a copy of the "Blue Book" (do a google search for Postscript Blue Book and it should be one of the first links) -- it has a lot of good examples and exercises in it. Should take about a good weekend to get the feel for it, then just keep a copy of the function reference from the end of the book printed out.
