I wouldn't call mine a "box" but it works the same way and has a much larger area for working on.

Materials needed:

glass top table

light stick

piece of board

1. Lay the board (I used styrofoam) across the cross members underneath the table so it creates a table.

2. Lay the light on top of the board so the light shines up through the glass table top. Plug in the light.

Voila! You're done.
