I've been seeing YUI3 Mobile presentations however I can't get to see any complete sample application like what we can find with jQuery mobile. Is there something like a "Kichen Sink" sample application for YUI3 for mobile? What I can see for the YUI gallery are just modules and not really a complete sample application.
I have learnt a lot from these two. Start with the Todo List, maybe implement it yourself. Then try to re-implement the Github-app. This app requires you to deal with more views and types of data.
It's great fun, but really, just start somewhere and use the docs to try/fail/learn/try/fail/learn.
