Stephen Hawking's apple

Went into central London with my daughter, spending a few hours at the Science Museum and then going to Six, the musical. We thought the latter was brilliant, but it didn't yield any blips. The blip is a glass apple in a recreation of Stephen Hawking's office at the museum. It was given to him by Intel on his 75th birthday and the coloured spots represent the Cosmic Microwave Background radiation map of the universe.
