Royal College of Art graduate Bilge Nur Saltik has designed dimpled glassware that creates kaleidoscopic effects (+ movie).

Pieces in Saltik's OP-jects collection are patterned with concave cuts around their lower portions, which act like a series of magnifying glasses and warp views through the glass.

When placed on a purposefully designed tablecloth covered in brightly-coloured triangles they create optical illusions.

Water contained within the vessels distorts the reflections further, so imagery is constantly changing while drinking from a glass.

The collection includes a carafe, tumbler and two different bowls. A set of rippled glass wall tiles were also created as part of the project.

Saltik studied on the Design Products course at the Royal College of Art and is exhibiting her glassware at Show RCA, which continues until 30 June.

Design Products course leader Tord Boontje recently announced that he will step down from his post in September after four years in the role.

More projects from this year's Royal College of Art graduates include bicycle helmets made from newspaper pulp and tools for musicians to change lighting and sounds at their gigs while playing their instruments.

We've also published glasses that reference patchwork quilts by Nendo and colourful tessellating glass tables by Sebastian Scherer.

OP-jects by Bilge Nur Saltik

This playful series by Royal College of Art graduate Bilge Nur Saltik contains daily life objects with optical illusions.

Presented at Royal College of Art graduate show in London this week, the playful series contains glassware, wall tiles and a tablecloth to reveal this secret, magical and playful lenticular effect. The function of the objects triggers the effect of illusions and it reveals hidden visual secrets.

"I am manipulating the information brain receives by distorting the image with layering different materials. Playing with colour and geometrical patterns enhance the optical illusions. These objects designed to change the pace of our ordinary life. They will surprise you by unexpected change and distortion on what you see during simply drinking water."

Glass pieces cut by hand to get concave cuts and sharpen edges. Different size cuts works like magnifying glass. They distort and multiplies the pattern underneath cause a psychedelic experience.

Bilge Nur Saltik is graduating from Platform 18 of the Design Products course at the Royal College of Art, where the show opens to the public from 20–30 June.
