[Sugar-devel] TurtleBlocks driving lego NXT 2.0 -

[Walter Bender]

Here is what I am thinking re TA extensions:

a palette class that can be used to both define a method of
determining if a palette should be present and the various blocks and
methods associated with that palette.

Should make it easier to support Arduino, Lego, misc. sensors, etc.

Comments?
