There's a painter named Robert Genn who sends out a Twice-Weekly Letter to artists all over the world. And it's free!
Though most of the subscribers are painters, I find his writings very thought provoking and insightful.
Here's an excerpt of today's letter titled The Peekaboo Principle:
I'm sitting on a bench eating coconut ice cream while keeping abreast of brain science on my . V.S. Ramachandran is a professor of neuroscience and psychology at the . Looking into various brains, including the brains of people who look at art, he's come to the conclusion that things are better when they are less visible. He calls it "The Peekaboo Principle." In his research, it seems that girls in scanty clothing are more appealing to the average straight male than girls in the buff. To be fair, these findings have been challenged by every frat house west of the Pecos.According to Ramachandran, concealment works because we are hardwired to solve puzzles. People get turned on by problem solving.
