From Francisco Inchauste, on the topic of UI that imitates realism:

It is so easy to love a certain effect and want to use that everywhere. Not all projects need to have the selections sitting on a perfectly lit wooden bookshelf. On one hand we want to be creative and make something that is appealing and can sell the product. On the other side we have to question the cost of that approach on the experience itself and balance style and function with purpose.
