This site is geered to people with a serious interest in sound waves. It did not appeal to me as much,but the information was good. And I believe in the arena in which it is used its won a lot of acclaim.I did bounce around the site for awhile.
Visually, the site was not as colorful as I imagined it might be. The information is extensive and well laid-out. I did however like the Rayleigh surface wave visual the best, very realistic looking.
