Today's submission is from Saul, a noted innovator and conversationalist.  Here's what Saul has to say about what's on his office wall:

In my case I have a big map which is a visualization of human history over the last 5000 years.  It is there because 1) I love maps 2) it's a great discussion starter: people who see it always comment 3) It reminds me of how late the US is to the global party, putting things into perspective and 4) it is a nice mix of cartography and art.
