I'm currently at a point in my career where I am really excited by digital design, by its fast-moving nature and its many unknown possibilities. Nine years ago when I first started university, apps weren't even around. As such, my tertiary education had a very strong print focus.
The bridge between print and digital design is where I like to sit because I do genuinely love designing for both. Although the design basics are the same across both, there are different things you have to take into account in digital design. One of those things is transitions between screens and between elements, which aid in learning interactivity as well as adding to a sense of delight to the user experience.
The reason I bring this up is because Marvel have recently posted a blog that I really liked about using gifs like this and this in prototype animations. A lot of the prototyping tools out there such as Marvel and Invision allow for basic transitions between screens but not within. I was also recently asked to use Flash to help developers understand the kind of animations I wanted on an interface. Except I've never needed to used Flash throughout my career so far. So I think gifs are a simple an accessible way (for designers) to be able to communicate these ideas earlier on in the process.
