Is a brilliant and easy to follow introduction to interesting problems in Theoretical Computer Science. It doesn't require any background knowledge and you can read it in a single sitting.

I believe I know of prior art for this. I used to work for a company called Security First Network Bank (The worlds first online bank) that went live October 1995. They had navigation bars in the bank summary, etc. The navigation bars were static but your account information was dynamic. It was www.sfnb.com (The link doesn't work anymore) but they got bought out by the Royal Bank of Canada who still uses the software. The company that wrote the webpages and banking software was Security First Technologies (www.s1.com). They may have patents related to the online software that would help.
