I found a couple old VHS tapes recently, and thought these two from "The IMSL Product Preview Series" were worth digitizing and uploading online, since I don't see them available anywhere, and I find they're very, as the kids say, "aesthetic". This was also a useful exercise in video encoding.
This one is a promotional reel from 1992 for exponentGRAPHICS®, a software library of graphical data visualization functions callable from C and FORTRAN applications. A rough scan of the case insert is available here: https://i.imgur.com/2D4B2qt.jpg
