ever used Day One? something similar there.
Reminds me of the pull to create list item in Clear
I like it though :)
I can also imagine this as pulling down another side of the cube. So it animates in another side of the app. I'm thinking of something like SPUN.
I love this idea and want to see a video of it in action.
Very much possible!
I like it very much too. I don't know if users would immediately figure out how to reach the Capture screen this way, however.
