Escalating box ( Eric Fuller)

The idea for the Escalating Box came from a couple of different mechanisms I'd been fooling around with. I was going to release them as two fairly simple separate boxes but realized that I could put them both into one trickier box. I made a poll on our Facebook Group and everyone overwhelmingly voted for a single, more difficult box. Done and done!

I got to the drawing board and realized not only could I put both mechanisms together, but that they would interact making the sum more difficult than the parts. Finally, just for fun, I added a third tricky lock before the final release move. Be careful what you ask for, facebook friends!

This is a fun solve, about medium in difficulty, and one that rewards progressive solving and manipulative experimentation. Construction is beautifully realized with a Curly maple box and several exotic wood options for the lid.
