An excerpt from http://www.sitepoint.com/atomic-fastest-way-design-beautiful-interactions/, by @mrdanielschwarz
Interaction design is the art of creating logical responses to a user’s action on the web. Whether you’re an interaction specialist, a user experience consultant, or a broadly-skilled web designer, it’s your responsibility to decide how a web element reacts to interaction and communicate that to the development team, even if you don’t quite understand the technologies that they’ll use.
But what is the fastest way to do that, without walking over to your developers desk and gesturing insane hand movements?
Also, what if you work remotely?
Atomic finally released their beta last week and it’s the fastest way of sampling an interaction idea and sending it out.
##Before Atomic
FramerJS, Origami and Pixate are some of the tools at our disposal already, but we don’t always want to code our interactions or test them on native devices, do we?
Atomic is blazingly fast, and if you’re coming from a Sketch App background, it’s even better. It mimics the same keyboard shortcuts, has the same intuitive snap-to features, and quite honestly it felt like I was using Sketch, only with the ability to prototype interactions.
