Just thinking about the stuff I post on Tumblr….
The graphics and animations that I post are experiments and often used in some other form as part of an entire visual composition - generally in live performance. They aren’t complete finished works like a demo reel.
It’s something like an electronic musician who would post a single bass drum sound that he/she created. It probably won’t be used alone but as one element in a piece of music. Still.. if this bass drum sound is something that the musician created - e.g. using a resonating filter through a VCA with an appropriate envelope - I would be inclined to find it worth clicking on and hearing. But that’s me. Some people might prefer to wait and hear an entire composition.
