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.

This one-screen prototype demonstrates some of Proto.io animation functionality.

These are the new prototypes for Floracaching. They are based on four co-design sessions, two at the University of Maryland and two at Brigham Young University.

Here's a demo showing a basic color picker using a container with 4 states for both the colored star and the color swatches.
