iTate Modern · Bankside
An immersive retrospective of seven decades of kinetic and interactive works, with light sculptures and geometric paintings that turn viewers into participants.
One 1959 painting looks at first like "nothing so much as a gingham tablecloth", in the Observer's words, then starts to flicker. Later you walk behind a red Perspex screen of reflective blades and watch your own silhouette break into pieces.
Le Parc, who died in May aged 97, days before it opened, gets more than 60 works from seven decades on Level 4 of the Blavatnik Building. It runs from black-and-white optical paintings through rooms of moving light to a games room of push-button pieces, and ends on colour. After years of "please don't touch" signs, this is the Tate show that wants you to press the buttons.
The Guardian found it "riotous good fun"; the Telegraph's Alastair Sooke called it "less fun-house, more laboratory of ideas". The catch is the last room, which the Observer found "kitsch", like "prog rock album covers from the 1970s". Tickets are £15 (£13 concessions, £5 on Tate Collective for 16 to 25s); open until 21:00 on Fridays and Saturdays.
Continual Light Cylinder (1962)
Prisms, mirrors, rotators and bulbs throw what the Observer called "a continuously changing aurora" of light around an enormous circle.
Vibrating Light, Tulles
Revolving shutters, net curtains and full-length mirrors make bars of light that feel like being inside a cage that is shaken up and down.
Screen with Reflective Blades
Walk behind this red Perspex screen and your silhouette splits into a row of fragments.
The games room
Push a button and Ribbons in the Wind unrolls its paper erratically, while Transformable Face rearranges itself with magnets.
Blue Sphere
It ripples lines of light over the walls and over you, though Studio International found its square room too tight to walk around.
You want quiet contemplation: many works are push-button games, and visitors crowd round them.
The Observer called it "art for the whole family", and kids can press the buttons that set the games-room works moving. Tate also runs a family tour of the show.
