Lava lamps found pride of place in bedrooms and living rooms alike throughout the 1960s and '70s. Then in the '80s and '90s there were those plasma globes that made your hair stand on end and scared the cat. These days, you have the Eclipse from Mathmos to satisfy all your 'interactive lighting' needs.

At the heart of the Eclipse is a series of LEDs that reflect their light off a metal sphere in the centre of a blown-glass dome. The LEDs then slowly cycle through a range of colours, and the glass dome subtly distorts the image as you move around it, giving a very striking effect. The Eclipse is available in two styles, Solar and Lunar, each with its own respective colour range. Best of all, you don't need a piece of white paper with a hole in it to view this Eclipse.
