(CNN) -- What will the cities of tomorrow look like? Decades ago, people imagined the future looking like an episode of "The Jetsons," with flying cars and buildings perched high atop stilts.

CNN iReporters sent in their favorites from their travels, including an amazing building designed to resemble a human eyeball, an American airport icon and a bizarre circular structure that defies the imagination.
