Been browsing the web recently with the “show tables” style sheet from a
bookmarklet at http://traumwind.tierpfad.de/blog/?detail=2002-02-20_15-07.
enforced as a user style sheet.

Basically, It just shows you all the table borders as thin red lines. For some
reason, I find that interesting. It reminds me once again that I’m glad I
don’t have to design web pages.
