Now I'm using SquareHome, which was released a couple of weeks ago, to make it more stable. 'Transparent-light theme' is applied and the 'people' group was composed with 'contact' shortcuts. The contact tile displays the photo in Google contacts when set 'auto image' as a form. While the tile for normal app shows the title image in Google Play (See the screenshots).
Currently, I'm using Xperia Arc, since the old nexus-one died.
The followings show the '3D effect' when scrolling horizontally.
The folder will appear from right side when clicked. See below.
