I love to tinker, not too much though as the kids and my wife do not like the clutter. POTBot came out of that interest. I like make thinks with my son and daughter, over Easter break we tried to make a walking robot. It did not quite work as we planned, but the fun was in the making. If you like DIY and tinkering look at link 1) below.
I also love to play around with GoogleEarth, it is a great tool and resource. There is a lot it can do and more I wish it could do. Ideally I wish it was more SecondLife-ish but that may be asking too much. Look at link 2) below to see how my geekness has fared on basic trial.
