KNOT and BRAID

Each of these HP48 files is a directory containing an
example of the HP48GX's parametric ploting functions.
These examples were inspired when I looked at the example
in the built-in 'EXAMPLES' directory and was quite
disapointed. I decided to try something more challenging
and came up with these two equation sets.

KNOT is a torus that loops back on itself and is tied in
a simple overhand knot. BRAID is three cylinders twisted
together in a standard braiding pattern.

Each directory contains a list of the GROBs for the
animation and a program called SEEIT which runs the
animation.

Also in each directory are the programs, equations and
settings variables used to create the animation.

For compatibility with the HP48SX the SEEIT program
determines whether it is being executed on a GX or SX and
either uses the inbuilt ANIMATE function on the GX or the
program ANIM inlcuded in both directories.

To exit the animation on a GX press the ON key, on an SX
press any other key.
