Light bulb keychain April 14, 2011

Lightbulb keychain. From my personal collection.

As I mentioned last time, I’m on the road. So what could be a more appropriate post to end this week than another smiley keychain?

Better still, this one comes from one of the academic conferences I like to attend (it was a give-away in the conference’s bookfair), and later this month I’m attending another conference. So: perfect!

Or should I say, Seemed like a good idea at the time? 😉
