20% project part 2

I was going to make an airsoft gun but my mentor and I found out it would be way to hard so, we decided to create a night light. It is a pyramid that has shapes that are drilled into the pyramid so if a candle is put in their, the shapes will show on the walls of the house.  The pyramid will also be painted so it has some color. I have not yet found out what colors I will be using but will try to find out soon.  Another thing is my mentor said that we will have to use geometry to get how big, long, wide, and etc. the pyramid is.
