From Homestuck, on my webcomic, mspaintadventures.com.
Obviously makes more sense if you are caught up on the whole story, but hope you enjoy anyway!
edit: Thanks to those who've watched it and left comments. The small file size is just the loader, the rest of the movie is about 50 MB, hosted elsewhere on NG. Tom is graciously helping me host this file for my site, and since it's already on here, I thought it would be cool to drop it in the portal.
If you're watching this and already read Homestuck, thanks for following. If you're new to it, hope you like it and will consider checking out the story. There are many animations of this sort, making much more sense in context.
