Happy anniversary, sketch blog

Three years ago today I posted my first entry to this blog. I was still a post doc then and would soon accept a position to teach chemistry at the University of San Diego in the fall as an adjunct while I got my illustration business off the ground. I'm pretty sure that the gift for 3rd anniversaries is a logo, so that's what I went with. Here's a sketch of the design I came up with. I'm replacing my original logo, which is based on the red dye molecule that makes alizarin crimson (but why would anyone know that, unless you happen to be one of those scientists you see on Nova who use IR to analyze old Rennaissance paintings?).  I like this new one better and I hope you do too.
