Tip of the Tongue consists of a table lamp, wall and ceiling-mounted sconce, all which feature an interesting illusion: a luminous mouth-blown opaline sphere appears to roll down the edge of a solid polished brass base. This delicate gesture of a sphere poised on the edge of the surface evokes the familiar phenomenon of failing to retrieve a word from memory, expressing a moment of tension in the form of the design. 

Tip of the Tongue was launched at Euroluce in Milan in 2013.
