An Idea Can Power a Light

"The brain is basically an electrical system. In fact, right now your brain is, on average, generating enough equivalent power to light a twenty-five-watt light bulb. It turns out that the old cartoon image of a light bulb appearing over the head to signify an idea was a lot more accurate than anyone imagined."

I like the idea behind this quote but at the same time it doesn't give the original artist enough credit. There is usually a lot more going on in a piece of art than is possible to see upon a casual glance or even repeated viewings.
