One Million Checkboxes
by @itseieio
One million checkboxes. That's it. The checked state syncs in realtime, so people had a lot of fun drawing pictures with the checkboxes and working together to check each individual box. All million of them.

Interactive Cloud
by @BalintFerenczy
A cloud. Why? Wrong question. Why not? You can move the cloud around, change the size, and adjust the weather.
Made a fun CodePen with an interactive cloud. Move it around, resize, set the weather. ⛅️🌩️

Gen Z Coding Video

I was mindlessly scrolling Instagram one day, as one does when they're over 25. And I saw this video. This video made me laugh. And I also thought to myself, "I bet someone could totally make that happen… wait. I bet I could make that happen."

Bad Video Player
by Christina Martinez
Inspired by those group projects we all hated in school. One person's input can negatively impact everyone else's experience. If you pause, we all pause. If you set your video to max volume in a public space, we're all listening at max volume right there with you. The playback rate is based on the average longitude of all connected users. And to set the volume, you need to make a noise inversely proportional to the volume you want. So, to get a quiet video for everyone, you must scream.
