Instructables is currently running the Coffee Cup Challenge, encouraging submissions for new Instructables that reuse paper coffee cups. Inspired by the contest, one user created this beautiful lamp pictured above using little more than coffee cups, a stapler, and a light assembly. See how after the jump.
When I read that the Coffee Cup Sphere Lamp used over 300 cups, my initial response was "get a reusable cup!" Furthermore, this particular lamp was created from new (not reused) cups. However, the project could be attempted using recycled cups, and would create just as beautiful a lamp. See other projects at the Coffee Cup Challenge (Instructables).
A few photos outlining the steps below. Visit Instructables for the complete how-to.
