At first when I saw this I thought “oh boy! yet another widget”. But, this has been a well thought out approach to the similar functionality found in Android and now windows with their metro styled interface. After viewing the demos, I found I liked the ability to combine the larger blocks with the normal icons. I could see that being pretty useful, especially if we have that capability built into IOS apps running in the background. There are challenges to IOS blocks in terms of maintaining a good battery life and memory usage, but nothing that can’t be over come with a good thought out design.
