The Matmos Air Switch lamp. Flap and glow. Kinda. £39.95.

‘For some unfathomable reason, waving your hand just above the rim of the Air Switch in a gentle, ‘These aren’t the droids you’re looking for’ fashion turns it on, whilst brightness is controlled via an up/down, Benny-Hill-slapping-that-bald-bloke-in-slo/mo movement. We really can’t overstate how impressive all this is.’
