Ask HN: Old side project sites still online that you're (secretly) proud of?

For New Year, I decided to 'audit' my personal domains for old sites that can be scrapped. One of the sites I found dates back 7 years - a small, interactive site I built to help promote my first novel[1]. As a promotion tool the site was a complete failure, but I remember spending weeks building it - using lots of shiny new-to-me libraries like Moment, Raphael and Cufon (for fonts) - and having great fun doing the work. So question: what personal sites do others have which, when they stumble across them again, brings back lots of fond memories?
