There are two widgets in the lower left and lower right corners of the page which constantly shoot little bullets all over the screen chasing your mouse pointer. In the steady state on my screen there are about 20 sprites constantly moving across the page. There was no obvious way to disable them other than inspecting the page and deleting the widgets from the page.

If you want me to read your site, and you want to put detailed technical information on it, please don't add things like this without an off switch.
