Tweetable SuperCollider code was popular for some time and I still love it. These snippets are called "SC140" - small SuperCollider patches with 140 characters or less. You can find a lot of them through the @sc140tweets account on Twitter still. Back in 2009, UK's the Wire magazine even did a compilation album with SC140s; the source code of its contributions can be found here.
SC280s (i.e. SuperCollider code snippets with less than 280 characters) were a thing as well.
Here's some of my own creations.
Also included is a file with a bunch of SC140 tweets that are not my own, but taken from celesteh's sc140 repo.
