[sugar] What does "undo" look like?

Nice idea.  Do clocks run clockwise everywhere in the world?  I think
clockwise-running clocks are pervasive enough that it may be safe to
make that association.

On the other hand, this may also lead to confusion in an activity that
deals explicitly with time (e.g. a music sequencer, a movie editor,
a calendar).

Maybe the leftward-hopping undo arrow is good enough if the arrow is
seen as a counterclockwise arc rather than a leftward motion?

I see that this is already open as #918: http://dev.laptop.org/ticket/918

This may eventually turn out to be a non-issue.  For example, even
though Chinese is often written top to bottom or right to left,
no one seems to have trouble with leftward-pointing undo buttons there.
They've just gotten used to them.
