Lights that replicate lightning, storms, clouds

Do any of you own or actively use those lighting fixtures that replicate some of the real world aspects like clouds in the sky moving around, lightning in a storm, and other aspects? I'm super curious on how the fish react (many may not really notice, however those that are sensitive to many light changes)? Do you see any additional benefits that may reflect a hugely positive success that would make you want to recommend these light to others, or is it just for the cool factor when people come into your house and see your aquarium replicating a storm, for example?
