I was listening to NPR the other day and they had a piece about an art exhibition in London that I'd really like to go to. Here's a summary about the radio piece from the NPR website:

A major art exhibition in London at one of the UK's top galleries is not open to anyone younger than 18.

"Seduced," at the Barbican Gallery, is billed as the most sexually explicit fine-art exhibition ever staged. It attempts to show 2,500 years of sexuality in world art, and to explore how attitudes about what is erotic art and what is pornography have changed through the ages.

When are scientists going to finally invent that Beam-me-up-Scotty contraption? Also, while I'm wishing ... I want the service or device to be reasonably priced.
