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.
