Lots of beautiful stuff.  I hate the interface that tries to do all
kinds of complicated and cutesy stuff with Javascript and Flash.  And
I get long stalls when fetching pages.  I don't know if I have the
patience.  I can look at any page in my nice little book anytime I
want without having to upgrade, reconfigure or tweak *anything at
all*. (See sig :-)

Something I saw in a book once that is neither in my (present) book
nor (apparently?) on that site:

  Imagine two solid cylinders (say, 4" dia), each with an axial shaft
  projecting from one end.  Shafts are in some kind of bearings.
  Orient at right angles, fairly close together, axes in the same
  plane, shafts away from the intersection of the axial lines.  Each
  cylinder has (say) 4 holes (say, 1/4" dia) parallel to the axis and
  at 12, 3, 6 and 9 o'clock.

  Now take four pieces of (slightly less than) 1/4" rod.  Bend each to
  a right angle, sort of like an allen wrench with equal legs.  Oil
  the rods and insert them in the holes so that they go around the
  "corner" from one cylinder to the other.

  As one cylinder is rotated, the rods slide in and out of the holes
  and one cylinder drives the other around a right angle.

  Gee, I wish I hadn't lost the book I saw that in.
