This thread has definitely intrigued me! After studying it for a few weeks now, I decided to make a "push-to" system for my LightBridge. It certainly won't cost $12, but its going to be cool! After many nights of calculations, I came up with a circle diameter that will work for me.
I went down to Staples and had them print the circle and then laminate it. I'll post my progress here, as it's going to take atleast a week to finish it.

Many thanks to all who have posted on this thread, and the many pictures to go along with.
