Competition: Dezeen has teamed up with TaliaYstudio and glassware company Lobmeyr to offer readers the chance to win one of four crystal pendants that double up as analogue photo filters.

Congratulations to the winners! Angie Aitchison from Scotland, Sofia Ioannidi from Greece, Adam Nathalie from France and Balla Dora from Hungary.

TaliaYStudio, founded by Vienna-based designer Talia Radford, produces interactive designs that propose lighthearted ways to use technology to promote physical and social interaction.

CrystalJellies is the newest addition to the existing JellySeries jewellery collection, and has been developed through a collaboration with Vienna glassware company Lobmeyr.

Each of the four pieces within the CrystalJellies range were inspired by chandelier pendants, and have been cut using different advanced glass-cutting techniques to create different kaleidoscopic effects.

The necklaces were launched as part of the Wien Products Collection – an initiative that brings together Viennese designers and companies – to coincide with Vienna Design Week 2015, which took place from 25 September to 4 October.

The first self-produced JellySeries range includes a collection of brass pendant necklaces that hold circles of yellow, cyan and magenta glass, which can also be used as camera filters and are primarily aimed at smartphone users.

The design studio has also developed a series of prototype high-tech "holdable" devices including a monocle that makes your eye look bigger, a digital lollipop that cheers you up and a camera triggered by a kiss.

This competition has now closed. Winners will be selected at random and notified by email, and their names will be published at the top of this page. Dezeen competitions are international and entries are accepted from readers in any country.
