Jer Thorp, an artist and educator from Vancouver, Canada, visualizes when people "wake up" on Twitter, or when they say good morning, rather. Here it is in its 3-d globe glory. It's called GoodMorning!. Notice the wave.
Okay, wait, I know you're already furiously leaving or thinking about a comment on how absolutely useless and non-concrete this is - and Jer is the first to admit that - but there is obviously something to learn here.
However, it's late, and I'm tired, so I'll leave that up to you. But off the top of my head, I'm thinking a more relevant subject like disease or need of help and color coding that's more meaningful. Your turn.
