Equipment for Mortal Engine has been shipped over from Australia
A spectacular laser show playing in Edinburgh has taken two months and £15,000 to ship its special equipment from Australia.
Australian contemporary dance group Chunky Move's Mortal Engine uses 1km of data cable across the Edinburgh Playhouse to create the show.
Technology including projectors, infrared cameras, smoke machines and lasers are used during the piece.
Two tonnes of equipment has been
brought for just three performances.
The show, which has mortality, sexuality, and desire as its central themes, receives its European premiere at the Edinburgh International Festival.
Patterns and sounds
Lasers and video projections respond to the dancers as they move.
The dancers trigger light patterns and sounds that appear to take on a life of their own.
Rachael Azzopardi, the show's executive producer, said it was the biggest show the company had ever created.
She told BBC Scotland news website: "Logistically this is a very big show and is the biggest we have ever created. We have been planning this trip since January so it is nice to finally be here.
"We are excited and honoured to be at such a prestigious festival.
"The technology which we use is so complicated we have been nervous it wouldn't work but so far it all has.
"Our software engineer is the author of the interactive software, Calypso, which he has worked on for 10 years, so along with this and our use of sound and lasers, we have created a very unique show.
"We have never had to send over this amount of equipment before so we have spent a long time planning it."
The risk assessment document for the show was 20 pages long.
On the night they need a total of six computers running at the same time.
The final performance is on Tuesday at 2000 BST.
