Create some minimalist graphic content for user manual.
Some screenshots, perhaps browser/proxy config, and
some of CGI editor pages. Maybe for fun, some before
and after screeshots from some really obnoxious web sites.
Maybe more fun, for home page, create animated gif that
starts as an obviously spoofed banner ad and then fades
quickly to transparent, or maybe fade to a nice Privoxy
banner/logo (if we ever get one :).
