Flex rockers have 3 characteristics:

1. the 4 altitude support points each sit directly above the 4 (not
3) azimuth support points

2. the rocker is made from thin plywood or metal tubing such that you can
easily flex it with your hands, ie, Greg Babcock's is only 1/2 inch thick
or so and made from a single sheet of plywood

3. the altitude rim extends down past the outside of the flex rocker,
almost touching the ground

Typically the ground board is a ring of wood or foam core or metal.  It
needs to be rigid since the rocker is not.
