Found this site  http://www.waterfountains.com/acrylic__spheres.htm . 
Still waiting on a reply for prices. Wonder if the acrylic won't melt 
at atmospheric pressure tho (high power needed, esp for 36"+ spheres 
or biggest I can afford (5-foot? lol). They also have huge steel 
hollow spheres to 79" for a huge vdg, at least by homegrown standards.
