  It is quite ok.  I have bunch of stuff in DrGeo window, and create a
script for a point and change its coordianate repeatedly by ticking
the script.  I get 15-19 fps, for example.

  "thinking silently", but I figured that my usage was not correct.

  I meant that Pythonists are thinking without making a lot of
discussions except a little bit on the python edu-sig mainling list,
which is... quite uninformative^^;)

  One long term "hope", "goal", or whatever that some of the members
at OLPC have is to make the laptop a "python" machine.  Like Lisp
machines or Smalltalk machines in the past but done "for" and "in"
Python.  In that setting, pushing a different language has always some
implications.  Kind of the same discussion again, but it is not about
which is good/not good at what.

  And, yes.
