Flat Coil Details

Somehow I missed the start of "flat coils". Could someone refer me to the 
basic construction details? I have seen photos on the net with a discharge 
from a wire in the center. Does this mean the outside is grounded? No ball or 
torroid? There is some 15kv insulated 18ga wire on eBay. It would be easy to 
wind a spiral between 2 plastic plates with it because of the large wire 
diameter (.09) but that gives only 100 turns for an 18 inch diameter spiral. 
Is that practical?
