About the "Wonderful Barrell". I, too, had been searching for a good notation
and some ideas about how to solve it. I finally found it! James Nourse, author
of 'The Simple Solution to Rubik's Cube' has a new book out entitled 'The
Simple Solution to Cubic Puzzles' (or close to that title). It goes for just $2, and
I picked mine up at a Waldenbooks. It includes a complete solution for the
barrell, as well as the pyramid, the picture cubes, the Missing Link, and some
items about the Rubik Snake. A good deal, but BEWARE of some most
aggravating typographical errors. (I know of two in the barrell solution.)
