The Flipboard animation created using states.

Basic To Do prototype based on: https://www.sketchappsources.com/free-source/3625-basic-to-do-app-design-sketch-freebie-resource.html

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

Project using Variables to simulate Drag and Drop to Snap functionality into a predefined area. While also adding Animations and States for a more smooth and elegant process.

First Project, just for fun..
