# Playhead Reel: Default

> A studio's archive: six projects, forty images. Scroll and the playhead walks the reel while each project opens into a collage under it, and the title rolls to the next as you cross into it. Scroll fast and the collage folds flat to let you skim. Hover a photo to lift it off the pile, click one to bring it under the playhead, or drag along the ruler.
