COTree is a physical installation that reacts on real time CO2 measurements in the surroundings. The latest version of COTree is a swirl plant which opens up for a lot of placement opportunities.

The plant physically moves and changes color to continuously blossom and wither. To do this COTree measures the CO2 level in its surroundings and muscle wire on the leaves retract or unfold. Meanwhile the heat created from the musclewire changes the thermocromatic ink that is painted on the leaves from green to yellow and vice versa. 

The viewer will experience a battle between life and death while COTree changes between decay and growth. The viewer is watching the fragility of nature. A fragility humans cannot normally see.
