And the winners are...

The results have been tabulated and the winners are in! In Round II of the Last Call for Google I/O GWT contest, we asked contestants to implement a countdown clock in GWT similar to the official Google I/O countdown and received 48 entries from the US (regrettably, other countries were ineligible due to contest legal requirements).

The three judges from the GWT team were very impressed with the overall creativity and productivity of the participants, with one of the winning entries coming in only seven hours into the 24-hr contest. We selected the top 10 entries based on originality, visual appeal, and performance, and used the size of the compiled Javascript as a tie-breaker in close calls. Here are a few of the judges' favorites:

Nine of our ten contest winners provided a little info about themselves, so in no particular order, here they are. Congratulations to all!

Hmm ... According to the Competition Rules, Canadians were not allowed to enter it. Oh well, nice results nevertheless.

Noticed the same thing Mohamed. I didn't even bother participating because Canadians weren't allowed, otherwise I would have at least tried :(

Oops, my mistake about the contest rules. I've corrected the first paragraph accordingly. FYI, the winners supplied info on city/state only AFTER the entries had been judged and purely for fun / informational purposes. I have not verified anyone's information posted here.
