Chuck Hoberman - Google Search Packs up small then you expand it in space [ame=http://www.youtube.com/watch?v=xRL0tMaNgjQ]YouTube - Original Hoberman Sphere[/ame]
I can't believe you have never seen one of these. I had one as a toy when I was around 10. Neat concept but not to useful unless you need to ship large empty spheres without skin.
Easy enough to skin on earth and reenforcement in orbit.the panels are all uniform I bought one for my kid when it was first available, the potential was rather obvious. Deck and bulk heads added as needed .
