The project contains numerous examples completed using variables and conditional logic.

Interactive banner with video of Google TV's home page. Must click to enable key presses used on a TV focus interaction model. The menu can be navigated but is only actionable for "For You" on the home page. Switching focus to the banner will enable additional UI and pausing on left/right interactions will allow for video playback with sound. No interactions below the banner are actionable.

Tumblr has a very nice series of animations that happens when you enter the compose mode. I thought it would be interesting to recreate this in Proto.io to show others how to achieve these kind of effect in their own protototypes. I have made a companion tutorial video where you can see exactly how I did it. This video is available here: http://docs.proto.io/videos/recreating-tumblr-compose-animations-in-proto-io/

If you need to get the Y position of a vertically scrolling container, create a text box. Then on the container scroll trigger, set a variable that evaluates the numerical callback value from the event (Y position). Then add a callback that changes the text property of the text box by reading from the variable.
