A Troupe With Tiny Opinions
Pip, Zing, Nova, Dot, Rex, Fizz, Blaze, and Bugg have moods, rituals, favorite little wins, and occasional theatrical complaints.
The smallest show on your screen
FleaWinder™
A tiny circus that follows you from desk to pocket to living room
Pip lifts. Nova balances. Bugg revs. The fleas remember little triumphs, write strange tiny notes, and turn ordinary taps and keystrokes into a show that feels alive. Free, private, and happiest when it is quietly doing something ridiculous.

The fleas have been busy. The newest Apple builds are warming up in TestFlight, the Mac show is ready to download, and the Windows classic build is still available for desk-side circus emergencies.
What changed →Meet the Current Troupe
It is still the smallest show on your screen. It just learned a few new doors, a few new memories, and a much stranger sense of place.
Small Shows Everywhere
The circus can peek out from your Mac, phone, TV, watch, widgets, keyboard, and the places where tiny performers clearly should not fit.
A Stage On Your Stuff
On supported Apple devices, the fleas can climb out of the flat strip and set up a very serious little show in your actual room.
Private Little Weirdness
The magic is meant to stay close to home: a personal desk toy with memories and jokes, not a profile of your life.
Eight Live Acts — Plus Your Own
Tightrope Walker
A daring flea wobbles across the high wire, jolted by every keystroke.
Trapeze Artist
Pendulum physics power death-defying leaps between swinging bars.
Cannon Show
Every mouse click loads and fires the cannon. BANG!
Strongflea
Each keystroke pumps the barbell higher. How high can you go?
Unicycle Rider
Speed and lean respond to your mouse energy in real time.
Juggling Flea
Three balls arc through the air in a mesmerizing cascade powered by your activity.
Fire Breather
A stream of flame erupts with every click—the more energy, the longer the blast.
Motorcycle Jumper
Bugg revs toward tiny ramps, clearing wild gaps and landing in sparks as your energy climbs.

How It Works
Every flea is an autonomous on-device agent. They decide their own actions, build their own memories, and — on iPhone and Mac with Apple Intelligence — speak in their own voice via the local LLM. Your typing and clicking still wind the circus like a music box, but the fleas have minds of their own.
Tap a flea to see their mood, memories, and who they're closest to. Step away and the troupe keeps living — wandering, watching each other rehearse, telling little stories, sometimes refusing your taps when they're not in the mood.
Zero configuration. No accounts. No servers. Every agent decision and every word of dialogue is generated locally on your device. Nothing is ever recorded or transmitted.
A Rich History
Flea circuses have captivated audiences for over 400 years—from 16th-century goldsmiths who harnessed live fleas to demonstrate impossibly tiny metalwork, to Victorian showmen who packed London’s Regent Street with miniature chariot races and cannon shows. FleaWinder™ carries on that tradition, digitally.
