We have this site in it’s newbie unprofessional and stripped down form here where you can even view the forum index and gallery. The forum doesn’t show its past layouts as bots that crawl sites only saw the basic one.

If you kinda want to see past versions of other sites:
Tiamat’s Manga Reviews
JanimeS – This site dates back from forever ago and it shows. JanimeS has come a lot way in many countless ways and remains modern.
Baka-Raptor – Great 2006 navigation bar there, sir.
Nico Nico Douga – Streaming video site with user comments on the video.

The Wayback Machine site is a bit buggy, slow, and often times unable to work. You also have a lot of Java-script, Flash, and similar missing. Just enter a URL in the URL address box and you’re set. Neat stuff.
