Back Blip - Good Advertising

My brain has sort of felt like a big blank white billboard these past few days.... I'm trying to get my head around a creative problem for work and it takes an amazing amount of energy.  This evening I was completely wasted as the problem hit a snag and I found myself again at a dead end.  The ride home didn't help with tons of traffic and rain. 

This white billboard was just what I was looking for though... :)
