A skate through cyberspace: on the edge with the Now Play This festival of experimental video games

This week, Somerset House houses a selection of avant garde games on the theme of liminality

For a week or so every year, Somerset House in London becomes home to a mini-festival of experimental video games: last year's were all on the theme of love. Now Play This has been running for 10 years, and this year's theme - liminality - is especially well-suited to the medium. Video games are in-between spaces: they are fictional worlds in which real-world relationships are made; they are an art form that exists across and between technology and culture. You could make a case for the inclusion of plenty of games in this selection, and the ones that are here explore the theme from some unexpected angles. There are games here about transition, expansion, life and death, borders, and skateboarding through cyberspace.

The variety of interactive experiences here is, as ever, huge, showing the full range of what games and digital art can be. There are relatively conventional pieces of interactive entertainment here - such as Ed Key and David Kanaga's Proteus, in which you walk through a procedurally generated dreamscape - and Sad Owl Studios's Viewfinder, a superb game about perception and photography. And then there's Labyrinth, a lattice of interconnected ropes that light up bright LED cubes when they touch, and a playable suitcase (Pamela Cuadros's Moving Memories). In one room a film about journeying to the broken, glitchy edgelands of the game Cyberpunk 2077 plays opposite a game (Crashboard) where you wear 3D glasses, stand on a skateboard and tilt your way through an obstacle course of pixellated imagery from the early days of the internet.
