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

Safe/Combination lock

Created using Proto.io library of fully interactive, native watchOS components.

The recently released Google Inbox app is a re-thinking of the email inbox experience that beautifully demonstrates Google's material design interactive animation language. This prototype focuses on the compose button's animation. Click the + to reveal a new state where a wave of buttons and labels float up, and the + becomes a pencil icon. It uses two states, with staggered animations.

Using variables on a slider to control the Brightness and Hue of a light bulb

Form validation using variables and states

This is an interactive dial pad, created with proto.io. Development & original idea: https://spaces.proto.io/akisioannou Graphic design: George Prentzas

An as close as possible copy of the IFTTT onboarding experience. This prototype is also made in 4 other tools (Pixate, Origami, Framer & Form) to compare the differences between them.

An extended collection of fully animatable UI libraries like triangles, stars, arrows and more, let you bring your idea to life all within Proto.io.
