This is wonderful to see. I was a student and then entered into the tech industry in the mid 90's and at that time the Internet had fun whimsical things like this almost weekly.
Obviously this was whimsical when it came out. However...we were creating synthetic data for training and testing OCR in multiple scripts. We would take a web page in some language with a non-Roman script, and reproduce it as multiple PDFs using different fonts. We also added various kinds of blurring, using ImageMagick and---of course---this very coffee stains program!
