Douglas Bowman's Stop Design website is back to it's full colour, fixed width glory. I have to say I prefer this to his previous "bleach" redesign. But like Dave Shea's Mezzoblue and my site, Doug has kept the older styles and you can view them. He has added a preference page where you can choose how you view the entire site.
I will eventually add such a stylesheet switcher so all the designs are available on every browser. Until then using a modern brower such as Firefox or Opera you can see the different styles per page. At present I have Havard's default design, an inverse colour scheme to this (very dark), and two older versions of trovster.com
