The Cameleon is a pavillion that uses Firefly to derive data from Pachube and uses this data to make a pavilion that reacts to the situation.
It uses color to show if the CO² level are safe. It opens and closes its skin to light, so if the light intensity are to high it closes itself. Also it opens its sides if the temperature is to hot so a breeze can pas through.
In the month oktober during the IE minor, Thijs van der Lely and Oswaldo Heinen used data from the Science Center Pachube feed to make a transforming structure using the Firefly plugin of Grasshopper3D.
