I used part of the "Laundry App UI Kit Sketch Resource" design that was designed by Satheesh Kumar at: https://www.sketchappsources.com/free-source/3397-laundry-app-ui-kit-sketch-freebie-resource.html to create a quick prototype

3 different counters using variables 1. A standard counter 2. A counter from the number of seconds the user sets 3. A countdown

This prototype showcases a new Proto.io feature called Gradients, it’s a new way to create and animate gradients straight in Proto.io. You can now make your UI pop with vibrant linear or radial colors, and bring to life with beautiful animations.

"No where To Go: Another Reality" is an app that will let you escape reality and will let you build your own world by using the features that the app have. The user will be able to become the designer, and they can navigate and see other people worlds. This prototype was done for a project in Graphic design major, Virginia Commonwealth University School of the Arts in Qatar.
