Hi Bill,
I've been looking all over the place, even on rooftops, for ideas for the
past couple years or more. So far all I've been able to think of is using 4
spheres connected by heating duct. It'd be somewhat square but the surface
would be relatively smooth. Thing is that 4 spheres would probably cost more
than a spun toroid in the first place.

I'm currently saving my nickels and dimes for a spun toroid. I figure at the
rate I'm going I should have enough by about 3 presidents from now. :)
