This is a sample of a relatively-generalized mouseover code, originally used (and, at present, still used) on http://tentacle.net/~deekoo/. I'm using an evil BASE HREF tag to make all the relative links work from ~deekoo/ instead of ~deekoo/laboratory/. Upon analysis, the copy here for review purposes is more confusing than the one out front is, hence probably less useful as research material.
