The hand-bent steel substructure of the sculpture is covered in a skin of incandescent light bulbs (new and burnt out), and rear-lit from within by 250 compact fluorescent bulbs, pulling a total power of approximately 20 amps (the equivalent of two household outlets  ).Each of these bulbs is attached to a pull-string, allowing viewers to control the illumination of the structure – like lightning in the CLOUD above them.
