I have a habit. Every few months I grow or shave my beard. My mother sometimes jokes that there's only one beard in our family, but it migrates between the males.
In the midst of removing the facial hair, I often find it amusing to half shave, or try on different (silly) looks. I'll shave all but the middle of my side burns, or test out the tough-cool look of a tuft of hair below my lower lip. I'll shave only the middle of my mustache, and the middle of my chin.
My wife likes the look of my beard, but finds it normally too prickly, which often prompts me to shave, as it did a couple weeks ago. Nothing spoils a romantic moment like "ow... ouch!".
I thought I'd try a little face lift on the blog. I may play around with the look a bit, or I may be lazy and just leave it.
***Edited to add:
I modified the header as well. I have long thought the blog title would transform into PhD Rainbow at some point, as I transitioned from post-doc limbo to tenure-track. Ah, the hopes. I'm still on the market, but more inclined to self-define my mission, than continue waiting for the magic wand of a hiring committee. Articulate... it's your ship, damn it... so steer!
