	I'm due to get another scanner. I have lots of pictures of the
place, and even did a sketch years ago of the pylon. I would like to whip
up some 3D models superimposed over that scenery to give a realistic feel
to the concept house. It really is a magical place.

	True enough that many places aren't suited for it, but this one I'm
talking about is. In fact, it used to *be* a micro-hydro place. (There are
still bits of old, destroyed machinery, pipes, wires to carry the
electricity out to the grid, etc.)

	This is really cool! And the funny thing is, I was just looking at
Billb's site earlier this week, for a different thing. He's got a cool page
on traffic waves at
which closely parallels my thinking on traffic theory, here:

	That Minto Wheel is a neat sounding gizmo. Not sure I need
*another* project, but that one might be fun... :-)
