Edinburgh International Festival has opened with a special event dubbed Deep Time.

The festival utilised the city's history castle, acting as a canvas for stunning visuals that traced the progression of planet Earth.

Deep Time honours the work of James Hutton, a pioneering geologist and a key figure in the Scottish Enlightenment.

The project was developed in partnership with 59 Productions and Edinburgh University, and features music from Mogwai.

The festival have just uploaded some footage – check it out below.
