This isn't exactly a fun game to play, but its amazing how they can create these flash animations these days. You can change the shadow angle and height, speed, leg width etc of the spider. You can make it follow the mouse pointer but if you get too close he will back off. You can grab him and drag him round by a leg. Even feed him some insects.
Now... if only they could add that similar Bush game to this one... http://www.onemotion.com/flash/spider/
