Speed of light/Arthur's Seat

There are many, many things going on in Britain is 2012 as far as art projects go, all for the benefit of the Olympic games.

This event will begin near the Olympics' end.  'Speed of light' (white horse theme) rears it's head again and guess what?  It's being held around Arthur's Seat in Edinburgh.
