Someone may have already mentioned this but I did not find it using the search term "floating icons". Anyways, with a picture set as a wallpaper if you hold the phone at a slight angle and move it around it appears the icons float just a little bit off of the wallpaper. Almost like the wallpaper is on a seperate screen under the screen that the icons appear on. I looked at a guys S6 phone and did not notice it but he had a theme wallpaper and not a picture. Maybe I am just a little crazy. Have a look at your phone and let me know if you see it as well. Stock TW launcher.
