OP-light by Bilge Nur Saltik creates luminous optical illusions
London Design Festival 2014: Turkish designer Bilge Nur Saltik has created a wall lamp from textured panels that rotates to form moving light patterns across its surface.

Bilge Nur Saltik, who graduated from London's Royal College of Art last year, used refraction to manipulate the light shining from her OP-light.
She layered three patterned acrylic panels in front of an LED light source within a circular frame.

The panels automatically begin rotating when the light is switched on, causing the light to distort in waves and create a "hypnotic effect".
"Each panel has a different size grid and each grid reflects light differently," Saltik told Dezeen. "When the panels are layered multiple reflections creates the moving pattern looking like water."

Powered by a small motor within the casing, the panels turn and swing in different ways.
Each of the acrylic sheets is also textured using a distinct geometric pattern so the light effects move in different directions across the top surface.

"Playing with density and the angles of the texture enhances the effect of the illusions," said Saltik. "When turned on, OP-light creates continuous magical and playful visual illusions of light."
Saltik designed the light as part of her OP-jects collection, which also includes dimpled glassware that creates kaleidoscopic effects.

The OP-light will be shown at designjunction from 18 to 21 September during the London Design Festival.
