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.

'Space tourism for everyone' “Earth is a small town with many neighborhoods in a very big universe.” ― Ron Garan Hey, here is my prototype which I made using Proto.io. Imagine that one day we all will be able to become space travellers.

Try it: rotate the circle with your finger (goes from 14 - 28) Help needed: play "tock" sound ONLY when temperature changes (every 30 degrees)

Interaction prototype of the image behaviour from the Facebook Paper app.

Done to explore setting colors with sliders and some Math expressions. Additional features, should anyone wish to build, would be to convert to HSV space, and to produce Hex color codes as well. To use colors, in the color controls of an element, replace the #XXXXXX hex code with this: rgb(255,125,45). Two swatches are provided, since color combinations are more interesting than single colors. Swatches are draggable.
