Hey thanks for the shout out! I was wondering when you were going to post results.
There are some really cool visualizations in the linked opani page: http://opani.com/ryan/elevator-analysis/results/#key=elevato...
I think the most relevant part of this for web folks is the gamification aspect (obviously its what I was interested in in your previous post). I'd love to see a version of this where you show 50% of users "play 20 times to get an easter egg" and give the other 50% no incentive. How much does it actually increase engagement?
