I've been working on the idea of these cubes for a while. First I was trying to make it into a pendant, but I couldn't work away the battery. I wanted to put the battery inside, but when you put something inside an object you're going to light from the inside, you can see the battery from the outside. So, pendants were off. Then I made a cube using regular paper. It's basically the same as shown in this instructable, but then with regular paper. It was nice, but didn't have that "wow" feeling I was looking for. Next I tried it with coloured transparent paper and I couldn't have been happier with the end result. I hope you like it!
