As part of the design process, figuring interactions (to me) is the fun and best part. Some of the developers might hate me for saying this but it's a great way to make your site more alive than just a flat UI. But it's also not an easy task!
This other nice redesign concept for a huge brand. This time Netflix was the target, a designer from Portugal called Pedro Cortés, made a nice work. We used to see design concepts with a lof of effects and wow effects, this is not that special or revolucionary but in my opinion is a design concept that is really possible to be made and turn to real.
This is an app concept that I made as an exercise and this is what I think the Netflix app should look like as it needs to be redesign and much improved, in my opinion. - Pedro Cortés
