Hey HN!
I made a site called living room. It's basically a TV that's shared across everybody using it. Anyone who's on the site can switch the channel, and everyone else instantly sees the change. The "channels" are just random live Twitch streams, so you never really know what you'll get. Sometimes, it's an esports guy, and sometimes, it's a sleep stream. And everybody watches it.
FYI, you can also shatter the TV screen.

Would love to hear your thoughts. Try it out with some friends (or strangers). :)
