Sketch-ing for a Pixate prototype

I just finished groing through Patrick Keenan's excellent 'Sketch With Material Design' article which got me reinvigorated about Sketch. I can't see myself going back to Photoshop for product design. http://www.smashingmagazine.com/2015/05/15/sketch-with-material-design/

This shot is mock-up I used to build out a Pixate prototype. You can see a small video of the prototype in action:
