I was browsing the page of Louis Clotman when I came across the Layout-o-Matic from InkNoise. This is not a new concept and has been done before. However, what makes this page so appealing to me is the ability to control the padding, body size and other elements of the CSS with just a few inputs. Check out this 3 column layout that I created using the tool.
Other tools offered by the site include The amazing Roll-over-er which creates XHTML compliant roll over icons and the List-O-Matic which creates complete lists that can be used in blogs, webpages etc and are controlled by various contributed code and CSS.
As always, thank them if you use their work!
PS: InkNoise also offers a cheap (starting at about 6 bucks) blogging tool/hosting alternative. The SXSW Community blog is powered by InkNoise.
