I've probably seen that picture before, but it wasn't a direct inspiration. We had a map like this for Firefox 3.6, so glow is a mix of that plus a little WarGames and Tron.
I only mentioned it because I thought you guys were using Zeus's Global Loadbalancers to distribute the load around the world. (Oh, and because I designed and built the original web-frontend for Zeus with little-lights-blinking-on-the-james-bond-baddy styled map).
We do use Zeus LBs. I am happy to report that one of the cogs that made this machine work much easier was the fact that we could have our zeus clusters send out remote syslog events for the site traffic in addition to the normal log files.
That made it easy for us to use rsyslog to filter the data and aggregate it to be consumed by the app.
