I remember as a kid I was fascinated by those seventies-lava lamps. Belgian designer Maarten de Ceulaer gave the lava lamp a (sustainable) twist with his Colour Lights. Okay.. there isn't any moving stuff in the Colour Lights. But they're very nice to look at. Maarten de Ceulaer uses food colorants, water, coloured LED's and glass laboratory bottles. The result, a cool effect.

“Any colour can be created by the right mix of the primary colours cyan, magenta and yellow. The spherical shape in the bottom of the bottles is sandblasted from below, so the power-LED below it, mounted on an aluminium disc, illuminates it completely.”

I want.
