All of the materials for this project can probably be found between a craft store, a home improvement store and a Radio Shack, but you can round a lot of it up for cheaper online. I got most of my supplies on ebay.
Personally, I made this because:
My bedroom has a light switch by the door.
My bed is not very close to that switch.
I have a lot of sharp metal sculptures in my bedroom, as well as a bed with unforgiving wooden corners.
I wanted something more special than an ordinary night light that could be used for the time between turning off the wall switch and making it safely into bed.
And it looks great between my Martian lunch box and little plastic dudes landing on the moon.....
*Apologies in advance for what appears to be incompetent photography - resin is very shiny and my camera lacks appreciation for reflective materials. It's also not that hot in the dark.
