Built the world's simplest code runner in 5 mins with Sprites.

This is doubly cool. First off, how it works:

User writes some scary JavaScript, which then gets run in a new Sprite. Sprites are literally built for running random code, so bring on the footguns.

Sprites make it easy to connect stuff on the internet.

Take Slack bots: easy to build, annoying to hook up locally and test.

Sprites are first-class citizens of the internet, so you can just build your bot on one, get a public URL, and boom: it's plug-n-play ready.

Is that a TUI for visualizing your sprites MADE IN A SPRITE? Yes, yes it is.

It lets you see all the sprites in your org, which ones are running, and organize them to get a better sense of which sprites work together.
