I just got a book that might be very interesting to cube lovers. It's
called "Bandaged Cubes", by Dieter Gebhardt. Some cube lovers may
already know Dieter and about bandaged cubes, from articles in the
CFF magazine; this is all about bandaging in one place. He presents
notation and classification, and discusses many types, the
group-theory of them, and how to solve them. It even has color pictures
of some of the variations.
One type is the C-block cube (also called "Rigit Edge Cube"), which is
just half of the Siamese cube recently discussed here.
For those who haven't seen articles on this, bandaged cubes are regular
Rubik's cubes with some edges taped together. If you tape 2 cubies,
one corner and one edge, that is an "A-block". If you tape an edge and a
center, that's a "B-block". 2 corners and an edge (3 cubies) is a "C-block.
And so on - he has notation for all the bandage possibilities, and
discusses (as far as I can tell) all the interesting variations in a
3x3x3. (He leaves 4x4x4 and 5x5x5 bandaged cubes for a later time.)
Anyway, if you get tired of Rubik's cube itself, these offer dozens
of variations, each with its own quirks and limitations, and many
chances for new discoveries.
According to CFF, the booklet can be bought from Dieter for $24 (DM 36)
(including postage) at:
Dieter Gebhardt
Norikerstrasse, 23, D-90402
Nurnberg, GERMANY
Its 100 pages, with 74 figures and 4 color plates.
I highly recommend it. Every Cube-lover should have a copy. (Of course,
now I need a cheap source of blank cubes to tape.)
