I was unsuccessful getting artsy types to vouch for counter rotating
wind turbines but I haven't given up trying to please our aesthetes:

1.  Find a clear structural material with the same index of refraction
as air.

2.  Find a paint that constantly changes color to blend in with
changing surroundings.

Back in the '50s DARPA had a top secret project called "Cameleon"
where a semi active paint could mimic any visual situation.
