When I went round to Arvind Devalia‘s place on Tuesday, he gave me a Rock Salt Crystal Lamp as an early Christmas present.  It now sits near my laptop.

These Rock Salt Crystal Lamps are meant to be natural air purifiers, made from salt crystal rocks formed hundreds of millions of years ago in the foothills of the Himalayan Mountains.  This one came from Light Impact – check out their site for more details about the lamp.
