We spotted: a Lightsaber progress bar in Spotify!!
Start the desktop client, Search for the Complete Star Wars Soundtrack in Spotify’s library, and Click Play. You will see the progress bar change to a lightsaber – click on the hilt and see the different models and colours.
The Lightsaber effect stays in place no matter what you’re listening to until you restart Spotify. If you don’t want to make a detour to the Star Wars soundtrack first, type “THX1138” into the search box to get the same result – that’s a <3 to the first film George Lucas directed.
