Today, as DC hosts Obama’s Inauguration (yey, it’s not the other guy, yey!), we bring you this very Presidential time-lapse, made for the occasion.

Behold, Chicago-based artist Jeremy Tubbs‘ erratic flip-book of 2,500+ photographs of the president, dated  January 1, 2008 to December 31, 2012, collected “from the internet” and arranged chronologically so you can watch him… get a litte grayer.

Maybe the grins are getting a little bit rarer.

Seriously, considering the job, he’s only getting slightly droopier as years go by. Must be all that biking. There’s biking helmet Obama in there somewhere, right? *Bicycle bell sounds.* Welcome back, Prez.
