Sean’s sp3 lamp is really lighting sculpture. Constructed from outdoor lighting fixtures, the lamp is controlled via an internal tilt switch – activated when the piece is rolled onto another one of its sides –

“sp3” is a term that chemists use to describe the hybridization of orbitals of a particular atom in a molecule. It is, generally, a fancy way of saying that an atom’s substituents are arranged in a tetrahedron around it. It seemed an appropriate name for this lamp, which is both tetrahedral in form and inspired by the tetrahedral, or sp3, carbon atom, which is the atom of which life is primarily composed.
