I'm in the process of mapping out Paris on my daughters ceiling, with the main landmarks printed in white to sit on the street map. Of course it needed a proper light. One that is a close to the real thing as I could make it.

This project requires a lot of printed pieces and a bit of cleaning up with a hobby knife. You'll also need to cut some plexiglass to glue the pieces onto.

When you have all the pieces smoothed out for a perfect geometric fit, you'll need to carefully glue them onto the plexiglass. I found that a few dots of Elmers Glue to lock them perfectly in place on some cardboard made the mounting of the plexiglass easier.

After you have 4 perfect triangles, you'll need to glue them all together in the pyramid shape. Getting a perfect square requires creating something like a cardboard square to hold them all together while lining up all the edges. I found that using a fair amount of tape to pull things together helped a lot.

Once you have your pyramid, it's time to glue your 8mm X 3mm neodymium magnets to the mounting brackets, then glue the mounting brackets onto the corners of the pyramid.

For the light itself you'll simply need a 12" X 12" square of sheet metal from Home Depot. Mount whatever small simple light you have onto this square and mount the square to the ceiling.
