Apropos of nothing, except that it’s very cool, here’s the project known as MÖBIUS, a “stop-motion sculpture” set up in Federation Square, Melbourne, in May 2011. They describe it this way:

MÖBIUS is a sculpture that can be configured into many cyclical patterns and behave as though it is eating itself, whilst sinking into the ground.

If you’re curious how it works, see the Web site of its builder,”an award winning art and design practice” named ENESS. (There’s a “making-of” video a little over halfway down the page.)
