I got the idea for this after seeing the one made by gmjhowe. The button on the side actually works, because I used a spring. Almost everything you see is held on by brads (little brass paper fasteners, for those outside the US). I used them because they're metal and I have no power tools to speak of. Sorry my hands look so pink; I know absolutely nothing about lighting or shutter speeds.
When I saw the thumbnail, I was like 'hmm, wonder if they were inspired by mine?' and I was correct!
You have done my original instructable justice.
Keep up the good work.
