My first Taxi experience!!!!!!!

I enabled the egg this past weekend and just now, between songs while listening to Bob Schneider on PTunes, the little yellow guy put-putted across my screen. Here I thought you all were just trying to fabricate an urban legend, and now I've seen the sign!!

It was kind of exciting, but it was over so fast, I'm not sure how I feel about the experience. Hmmm......

Question:

My taxi went from right to left on the screen. Is this because I reside in the northern hemisphere? Does the taxi go from left to right for our friends "down under"?
