What do crows like? Shiny things. Us humans are not that different, which is why most people prefer using visual interfaces instead of command line terminals.
We love good looking, fluid, modern, responsive, and touch-sensitive applications which provide feedback. We geek out over good looking animations and apps that come alive as we use them. In short, we love our apps shiny.
As developers, too often we focus on functionalities and just getting things done. If a user story or client requirement is completed and it works, we will pat ourselves on the back and call it a day. But what if we spent just a few more minutes to make things - you've guessed it - shinier?
