Note, may not be compatible on Android 6.x Marshmallow and some devices running previous Android versions
Editor's Notes & Price Research
Described as an "...innovative multimedia exploration of music, nature and technology by the musician Björk," this app has earned a 4.6 out of 5 star rating in over 370 reviews ~RevOne
Regular price was $12.99, now free.
Note: this says not compatible with my Nexus 5x running Marshmallow (6.x), but it worked fine on a KitKat device.
Also note that this is a monster app, and the final download was approximately 475MB. If you don't have space on your phone or device, either clean it up first or don't even try.
