Wired: oranges. Tired: peeling oranges.
I posted the embarrassingly simple script used for Random Web Search on the software page. It’s very stripped down and doesn’t do cool stuff like check to see if the word has already been added — that was added later on with help from a Perl guru at the office. But this initial pass is totally self working. Just drop it in your cgi-bin and add your site address to the script.
