Nebula12, Micasa LAB
This weather-forecasting lamp creates an indoor cloud to warn of grey skies outside.
The Nebula 12 by Swiss design studio Micasa LAB combines liquid nitrogen and hot water to create a billowing cloud of steam, which is kept in circulation around the lamp by vacuum suction.
The form the cloud takes and the colour of the lamp depend on the weather forecast for the next 48 hours.
A grey cloud appears on an overcast day, while a patch of low pressure is signalled by a red light seeping through the cloud. On sunny days the cloud disappears, leaving a warm yellow light, and at sunset the light turns warm orange.
