I would really like to get this app I’ve been dreaming about for years off the ground. It brings together fans of “Sandstorm” by Darude by issuing successively longer and louder clips of the song as you get closer to other app users. Within close enough proximity the whole song plays on a loop and the screen and camera flash goes off to the song on all phones and a dance party starts.

It’s also installed on every phone on every OS and default active at all times…which is maybe Elon crazy but definitely Grimes-fun.
