Pavel Fuksa and Barbora Idesová shared a really cool illustration and motion design post on their Behance page.
There are quite a few things I like to do before opening my computer and using a design tool like Sketch of Photoshop. One of the first things I do is a competitive analysis and right after some simple mood boards with references for things like animation, typography, colors, simplicity. I feel that this step gives me a broader view of possible solutions done by other designers. The process is simple, I just collect as many images as possible and the those that I think are the best fit for each case.
For this post I want to share some simple images of UI animations. They are from Pinterest and Dribbble. I used them as references for some personal projects I am working on. The cool thing about this images is that they are pure visual and motion references. I don't pay attention about technical feasibility or anything.
