The lamp Cobra of Elio Martinelli, the designer of light, with its sinuous and dynamic lines represents a successful mix of creative intuition and experimental production. The swivel table lamp, with direct light oriented downward, conceals behind the immediacy of the image, brilliant geometric solutions. Cobra is characterized by a sinusoidal configuration that seems to crystallize the ledge of the snake ready to attack. A powerful graphic sign, of organic matrix, which reinterprets the multiplicity of natural forms through the aid of technical progress.
