Time magazine named indoor Clouds created by Berndnaut Smilde fascinating idea and its implementation as one of the Best Inventions of the Year 2012. "It requires meticulous planning: the temperature, humidity and lighting all have to be just so. Once everything is ready, Smilde summons the cloud out of the air using a fog machine. It lasts only moments, but the effect is dramatic and strangely moving."
