The common theme is that most of them are wide at or near the bottom and they don't hang too far from the ceiling. Most important, they have multiple bulbs and light up, down and to all sides.
For reference and discussion purposes, each light has a number beneath it.
|A2 - How do you change the bulbs?|
|A4 - This is about 9 feet across and came out of JFK airport.|
|A5 - Venini, I think.|
|A7 - Maybe a little baloonsy.|
|A9 - Enormous, but scalable and could be shorter top to bottom. Also, pretty simple to construct.|
|A13 - The "Artichoke" light.|
|A14 - These style are all called "Sputnik" light fixtures.|
|A17 - I think I could make this out of bundt pans.|
|A19 - Too yellow, and too 70's.|
|A20 - Inexpensive copies of this are available for around $350.|
|A21 - Looks like a bug pod with hatchlings trying to get out.|
