There's a lot of good turtle stuff out there in Python.

Gregor is a resident master.

My sense is there's no shortage of anything except a willingness to try new

Innovation is hard to accomplish at the end of the day, simply because it's
easier to keep doing what you were doing  -- until it's not.

Freeing up schools to try new things means not locking them in to
pre-specified curricula complete with state mandated texts and tests.

Not everyone has such freedoms.



I've got very primitive "tractor" objects in a field of ascii, just to show

One of the freakiest tractors is a generator that implements the "send"
feature in a weird way:

(you can refuel it, change direction, change the mark it makes when it
