Geocities-izer is a tool that makes any web page look “like it was made by a 13 year-old in 1996” – awful colors, illegible text and animated GIFs. This is how Instant Fundas look. Ah! my eyes!
Actually there are 3 themes and 12 music variations that the site randomly applies to any site you want to Geocities-ize. You can edit the URL to apply any one of the themes (numbered 1 to 3) and/or music (numbered 1 through 12).
