I didn't look at the source, but I'm guessing that it is seeking the floppy drive because whoever made the site included an image that was just on the floppy disk in his/her computer at the time. The site doesn't exactly look professional, what with the dancing Santas and all.
(edit) Yep, there's a link to an image on the a: drive. There are also a number of images hosted on other servers. And the title is misspelled (which Blue also used, nice catch Blue!). I may have to go and make me a proper INTERNATIONAL CAPS LOCK DAY site.
