There are many, but my vote goes for flat 3d [0]. It is a natural progression from purely flat. It adds more context, and gives the designer more room (an extra dimension!) to be innovative without being intrusive.<p>Flat animated is sort of where it is at now. Google&#x27;s material would fall under flat animated as well as much of iOS 8&#x2F;9, but drop shadows and gradients are better replaced with subtle tones and accenting along the lines of posterized Anime art [1].<p>As a designer if you can make Google and Apple&#x27;s latest efforts look dated, you&#x27;ve done an excellent job. Flat 3d sort of does that.<p>--<p>[0] <a href="https:&#x2F;&#x2F;www.google.com&#x2F;search?q=flat+3d+ui&amp;es_sm=93&amp;source=lnms&amp;tbm=isch&amp;sa=X&amp;ved=0CAcQ_AUoAWoVChMIjIeKyPbWxwIVTpeICh1fegKp" rel="nofollow">https:&#x2F;&#x2F;www.google.com&#x2F;search?q=flat+3d+ui&amp;es_sm=93&amp;source=l...</a><p>[1] <a href="https:&#x2F;&#x2F;www.google.com&#x2F;search?q=posterized+art&amp;es_sm=93&amp;source=lnms&amp;tbm=isch&amp;sa=X&amp;ved=0CAcQ_AUoAWoVChMI38rivvnWxwIVAk6ICh2wDQhM&amp;biw=1502&amp;bih=1212" rel="nofollow">https:&#x2F;&#x2F;www.google.com&#x2F;search?q=posterized+art&amp;es_sm=93&amp;sour...</a>
