Funky New Art Commission, CO2morrow, for Royal Academy

London's getting a new public art work next month. Eight metres in diameter and called CO2morrow, we're told is inspired by a zeolite, a brilliantly named "scrubber molecule" because it scrubs carbon dioxide from pollution sources. (But you got that from the picture, right?)

You can catch the new piece of art on the side of the Royal Academy building, 6 Burlington Gardens, lit by 1,440 LEDs from 3 December. It coincides with the RA's GSK Contemporary, Earth: Art of a Changing World exhibition and it's been commissioned by the RA and the National Trust, collaborating for the first time. The chaps behind it are Marcos Lutyens and Alessandro Marianantoni.

Pretty, different, a bit virus-like and science-y; and if you're one of those people who likes their art to do something, you're in luck.

CO2morrow will show the changing levels of CO2 in the atmosphere. The LEDs within the sculpture are set up to reflect the CO2 readers at National Trust properties around the country, which route their readings (via a university environment department) through to the RA and the twinkly lights you can see.

And like the current Anish Kapoor sculpture in the RA's courtyard, CO2morrow, will, of course, stand as a great big advert for the exhibition going on inside. Clever old RA...

GSK Contemporary, Earth: Art of a Changing World, is at the Royal Academy, 6 Burlington Gardens, W1, from 3 Dec to 31Jan. Tickets from £3 for kids; from £4 for adults.
