Playing around with some ideas around remote presentations. The idea is that you can author a presentation here, share the URL with someone, then advance slides from your browser and it will advance in theirs as well (through the magic of websockets/liveview). This is much faster and more efficient than, eg, sharing your screen in Zoom while you go through a slide deck.
(there's also a separate chat room feature that was initially just me figuring out how liveview/channels works but I might turn into a backchannel feature on presentations).
