Someone sent this one in to me and after viewing it, I thought it was fun and nerdy enough to post on the site. This infographic is a visual representation of Pi which as you know is approximately equal to 3.14159265. You do know that, right? No?!?
This infographic should explain everything to you, but most likely not (this is super nerdy), so I also recommend that you watch this weird video about Pi too.
