I'm in process of buying a house so I'm a little all over in the place with lots on my plate. Having said that:

I want to thank everyone who entered the competition. It was great to see so many entries - in particular on the last day :)  The judges are examining each solution in detail and its going to be tough selecting the winners from a number of interesting entries - very cool stuff. Hopefully I'll have more time in 2-3 weeks once this house thing is done.
