[OLPC-Games] Micropolis source code release!

[Samuel Klein]

Fantastic.  A separate cellEngine is more than I was hoping for :-)
Now we need a Micropolis wall in the office with various
games-in-progress... a fine use for some of the B2s we have around.
How's the discussion of reworking and opening the city-devlopment
rules coming?  Have you talked any further with Alan about that?  Some
class might want to take on a 'Post-modern SimCity' research project
for the spring term now that it's possible to easily play with those
variables.
