The Const Lamp is the creation of Thinkk, a Thailand based studio. The lamp was created from three simple elements: base, body and shade. This simplicity is echoed through the use of marble and and ash wood and the bright colors the shades are painted. The pairing of these materials make for a lamp with a beautiful and compelling form. I also think the slots for the pencils in the marble is a really nice touch, showing that no matter how refined the design is, you can still have fun.
