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

I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

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/
