ResQ - Ebony Version

From cubicdissection.com:

ResQ is a unique Sequential Discovery Puzzle based on Boucher's brilliant Visitor Q We took the original design and modified it by adding additional goals, tools, and tricks. ResQ is the result of nearly three months of prototyping and features previously unseen concepts and hardware.

The brilliance of Boucher's VQ design is in the depth of possible movements and states the puzzle can be in. Visitor Q is very much like a maze; you find configurations that won't allow you to progress and must back-track to find another approach. I can't overstate the sophistication and elegance of VQ. To the extent ResQ turns out to be a good puzzle, it's because I was standing on the shoulders of a giant.

Solving ResQ requires imagination, analysis, close observation, a bit of dexterity, and a lot of exploration. A minimum of 70 moves is required, with no upper limit.
