The newest update to the Google Play Launcher now enables a Lollipop look and feel on older Android devices. Previously, the Google Now Launcher would only have a Lollipop flavored theme if your device was running Lollipop; today that changes. Now, if you have an Android device between 4.1 and 4.4, you can get Material Design on your phone.
You will be able to notice the updated Google Search Bar, Google Now cards, as well as the app drawer. This is great to hear for users that are craving for some Lollipop flavor on their KitKat and older devices. Although your homescreen will look different, remember your animations will still be stock. If you can’t wait for your phone to get the update, this will at least hold you over for awhile.
