Ever wanted to shout something without actually shouting? Meet your new best friend: this smart programmable message cap. It’s got a color LED display that’s basically a billboard for your thoughts (or your brand). Hook it up via Bluetooth—no wires, no fuss—and tweak your message on the fly with the app. Whether you’re at a game, a protest, or just trying to make your dog laugh, this cap’s got you covered.

- Updating your message is easier than deciding what to have for lunch, thanks to the app’s dead-simple interface.

- And the battery? It’ll last longer than your phone’s does, guaranteed—well, almost guaranteed.
