Colourful perpetual wall calendar by London graphic artist Yoni Alter

Now he's just launched a new Perpetual Wall Calendar, available to buy from his online shop, crafted using natural ash plywood, wooden dowels and plastic cards. "It's fun to change the stacking orders behind the frontal cards and get different colour combinations," says Yoni.

Yoni studied art and design in Jerusalem before completing his MA in Graphic Design at the University of the Arts London. Today, he calls London home – somewhere that is a constant source of inspiration for him. Indeed, Yoni’s debut London show at Kemistry Gallery was motivated by the city’s urban landscapes and architecture. And his colourful depictions of London architecture (along with other cities) can be enjoyed in his ongoing series, Shape of Cities.

The Perpetual Wall Calendar costs £145, is made in London and comes flat-packed. Find out more at yoniishappy.com.
