Fantastic Site

You have a fantastic site.

I spent hour after hour browsing the site with the same fresh attention. It's helping me a lot with my son's tennis.

John,

I love the site and have really appreciated what I have learned from it. I love the incredible factual insight gained by analyzing high-speed video of tennis mechanics that were previously impossible to actually see by eye.

You get to be like Galileo who pointed his newly-invented telescope at sky and made discoveries where ever he looked.
