for embedded scripting and feature interaction checking.
Tope has completed another form of rule based controller and
generated several short position papers.
Daniel has completed porting the Pebbles software to the Molly cards
and has built several hardware Pebbles (clock, DVD player, LCD display
and so on). He has got Pushlogic working on these cards and now
developing some network applications.
We manned a Pebbles stand at the CMI show held in the Gates
building in April 2004 and again in 2005.
In general, we are putting together an ever growing number of
Pebbles and the applications are following on.
The next steps will be further publications and dissemination
to industry through CMI.
