Well seeing as how I have never created a sphere world either, thanks for the heads up =D.
Anyway the "around the sun" thing is a matter of semantics. Around to me means around the sun in a dyson sphere.

I guess I watch too much Star Trek or B5 or Star Wars or whatever =D. Actually I only remember seeing a Dyson Sphere in Star Trek.
