A maker created an ASCII-style aquarium for a smart-home display. Fish made from characters swim across the screen, including one that shows a live sensor temperature. Home Assistant can trigger falling food that the fish chase, and users can adjust fish count and swimming speed. A Halloween mode replaces fish with pumpkins, ghosts, and other spooky icons, and a scare effect displays an image and plays a sound. The panel can also show a voice assistant's state.
A smart-home dashboard now reports the temperature through a swimming fish—and gives you virtual fish to feed.
A Halloween skull uses a camera to spot people in costumes, then generates a dad joke tailored to what they are wearing. It sends the camera image to Claude and reads the generated joke aloud using text-to-speech.
Liz Clark of Adafruit published the build guide in 2025. The project is intended to entertain costumed guests at a Halloween party.
Approach a spooky skull and, instead of scaring you, it tells a dad joke. That's one unusually cheerful Halloween monster.
