do you happen to have a link to the upd8 vines or maybe caliborn's vine account???

They aren’t actually vine.

1. the sound icon in the corner is the one used in the other Homestuck flashes, not the ones located on vines.

2. Vines have their audio buttons on the bottom right corner, not the top left.

3. Vines always link to their vine page even if embedded.

4. If it was an actual vine it’d be viewable on ios devices.
