A little while ago, I did some interactive expanding ad banners for XM Nav Traffic with live traffic updating on the latest Lexus vehicles. You might run into the ads on some car enthusiast sites, or you can check out the message board, lederboard or skyscraper here. When the banner expands you can play with the sonar map to control the speed of travel. Some really cool randomizer programming makes the pretty shapes fly by. Fun stuff.

Wish I had XM Nav Traffic with live traffic updating on my car!
