Very cool site - ptable.com

I normally don't go into site promotion but rather concept info. But I think this is a web page worth looking at in technical writing. It is a dynamic periodic table. I really appreciate the work that went into this page. The site, ptable, provides quite a bit of interactive viewing and information for the reader. Click on just about anything and you will be given details and new views. This site is why I like the web as a learning, training, and dissemination of information tool.

There's a video on using it too.
