Super easy and uses stuff that you already have! Also a great geeky gift!
Step 1: Materials
What you'll need:
Empty tissue box
Any type of light (as long as you can stuff it into a tissue box)
Several sheets of thin plastic
An X-Acto knife
Step 2: Tissue Box
Once you find an empty tissue box cut the plastic off around the hole.
Step 3: Covering the Tissue Box in Tape
To paint this tissue box later on, you're going to need to cover it in painters tape first (unless your tissue box is solid gray)
Step 4: Design
Sketch a design (similar to the papercraft pattern above) on all of the sides except for the side with the hole in it, that is the bottom.
Step 5: Cut Out Design
With the X-Acto knife, cut out the design you made on all of the sides but the bottom. This part may take a while, and you might have to fiddle with some parts of the box.
Step 6: Paint
After you've done this paint all of the sides (including the bottom) a solid gray color.
Step 7: Plastic
Cut squares in the plastic that is a bit smaller than the sides of the box. Tape each one on the inside of the box so the design has plastic behind it.
(I had already moved on when I took this photo...)
Step 8: Color It Red
With the red sharpie, carefully color all of the showing plastic red. (It helps to do small up and down motions)
Step 9: Light It!
Now, all you have to do is put the light in! My light could fit into the hole sideways and not fall out because it was slightly larger than the hole, but if your light is smaller I would recommend taping it in place or adding another piece of cardboard that the light could go through.
