Yes.  Point taken. I bit my tongue even as I typed those hazylazy words "new
paradigm". Let me re-phrase.. This looks like a good idea, and I hope is
progress.

mmm yes. Let's go Egyptian
string sand and sea shells :-)

For years I treasured a little second hand Russian pamphlet I found on the
Charing Cross road. 'Geometry with [only] rulers and compass' - meaning
straighedge no measurements or protractors.

A similar epiphany, but a lot more complex+expensive, was seeing Tom Davis's
'Geometer' running on an SGI for the first time about 10 years ago.

...which perhaps proves that this stuff really goes to your head!
