Infinity Lights

How are you familiar with infinity lights? Infinity lights are self-assemble lampshades made up of quadrilateral, interlocking pieces that can be assembled in a variety of ways. The most popular configuration is the sphere, as seen below. Price range between $20-$60.

We saw this display at our local mall. I thought they're cool and unique. Now my daughter wants one for Christmas. I'll think about it...lol!
