Reddirama by Baablebrox

Reddirama turns Reddit into a fullscreen, hands-free slideshow you can lean back and watch.

Pick a source and lean back:
- any subreddit or user profile (just open Reddirama from its page)
- your Home feed
- your saved and upvoted posts (logged in)
- your custom feeds (logged in)

Images, GIFs, galleries and videos play automatically, with adjustable speed, sound, and video scrubbing. Sorting adapts to the source (newest / oldest / shuffle for saved, upvoted and profiles; best / hot / new / top for Home; hot / new / top for subreddits and feeds).

How it works: Reddirama adds a button on reddit.com. What it plays depends on where you tap it: a subreddit page plays that subreddit, a profile page plays that person's posts, and the menu in the viewer lets you switch source anytime (logged in, it also offers your Home, saved, upvoted and custom feeds). It reads the chosen listing through your existing Reddit session and opens the slideshow in a separate viewer page. Nothing is stored anywhere, there is no extra login and no Reddit app to create. Your data flows only between you, Reddit and the viewer.
