Device that Produces Rainbows

Rainbows are beautiful and that's it. Children enjoy watching these creations of nature, but one man thought that it would be better if people could see rainbows more often. This is why he has come up with a machine that creates rainbows.
Artist Michael Jones McKean has been testing his device in parks where he shot small rainbows across the sky. Now he looks forward to developing a machine that would generate much larger rainbows with the help of reclaimed rainwater and sunlight.

His studio is located at the Bemis Center for Contemporary Arts in Omaha, Nebraska.
