The Rake's Progress

Some people didn't get this one at first when it ran a few weeks ago. You have to look carefully at Eightball's rake since it adopts an optical illusion known as a blivet (or Devil's Tuning Fork). This usually has only three prongs so it was extra difficult to work out how to do it with six since one of the lines cannot be attached.
