With iOS7 Apple introduced a completely new design for the 6 year old OS. Among all the changes, one that really caught everyone's attention was the blurred background effect. Basically some parts of the UI get a nice frosted glass effect. There are a couple of ways to achieve this effect using HTML and CSS. The easiest way is to use CSS filters, however the performance on phones is far from usable. With that in mind I decided to experiment with Canvas and the result was quite good. So in this post I want to share a little bit about the idea behind this prototype.
