Invent a machine that makes the world feel a little less loud.
It doesn't have to be realistic. Honestly, it's better if it isn't.
Maybe it runs on tea steam. Old buttons. Moss, music, moonlight, tiny gears powered by sighs.
A few to get you going: a machine that turns notifications into bubbles. An engine that melts overthinking into warm light. A little robot that files unnecessary worries under "not right now."
Make it however you make things. Draw it, collage it, sculpt it, build it from scraps, or just write the description. Give it a name if one comes to you. Tell us what kind of noise it quiets.
Then drop it in the comments!
