The S7 and S7 Edge go live tomorrow, but you can get a taste of the S7 experience right now on your Galaxy S6 or Note 5! Developer "Albe95" has put together an S7 apps package. There are 6 apps included so a few things are missing. Unfortunately this does not include the Always on Display from the S7.
In order for this to work you must be running Android Marshmallow 6.0.1 on your S6 or Note 5. Apps included in the package are the S7 Game Launcher, S7 Galaxy Labs, S7 Weather Widget, S7 Wallpaper Picker, S7 Galaxy Apps and Widget, and the S7 Theme Store. Head to the link below for the full install guide and download links.
