Trial in adding graphics and animated images.

Here is some html code I discovered at http://abowman.com/google-modules/dog/. There are a few interesting ones, but this one really caught my eye. The animated image of the dog will respond to the items at the bottom of the screen. Try throwing some doggie treats or a red ball, and watch what happens. The html coding is complicated to the eye, but the results are eye catching.
