Ok, I will admit that I am really bored right now.
I went to this site and you really see nothing but the bugs
Any way if you want them to move just keep refreshing. Now that does not work either so. Keep the screen centered where you want and keep your cursor out of the way so it will not flutter around, print screen, paste, then go back and refresh. Do this several times and save it as a gif or I just previewed it in animation shop.
Yuck!
Any way off to fine something less gross to do.
Oh yah, the site.
