While you can create your own "scenes" within the official Philips Hue app, OnSwitch comes with a handful of pre-made scenes for just about any occasion or mood.
The app includes both animated and still scenes, each of which offer unique experiences. For instance, there's a scene called Sahara, which changes the color of your lights to look like you're in the desert. You can even change the style of your bulbs to things like halogen, antique, night light, etc.
OnSwitch also includes a sunrise feature, that automatically turns on your bulbs and slowly brightens them to replicate a sunrise in the morning.
