Ever since I went and saw Olafur Eliasson's take your time exhibit at the MCA a couple of months ago, I've been obsessed with light installations ever since. I believe alot of this is due to the healing benefits of light/colour, known as chromotherapy. Several ancient culture such as the Egyptians and Chinese have been documented as using this practise for centuries. For instance red can be used to stimulate the circulation of blood in the body, while blue can be used to manage pain. So next time you gotta cold, ditch the doc and chuck some fluorescent filters over your lights instead!
