MPavilion 2015 roof 'petals'

"The canopy is made up of 13 large petals and 30 smaller petals with diameters of three and five metres. Each petal is just two millimetres thick and is attached to the top of a network of 95 carbon fibre stalks that allow the canopy to sway gently in the wind." – Dezeen: http://bit.ly/2kXzOZT
