Your party, on the wall.

A live music visualizer for the biggest screen in the room — the TV you already own, or a projector aimed at a wall. Play the music you were going to play anyway. Dancy Ants listens and paints the room to it — in your browser, nothing to install.

What it is

Visuals that move to whatever you're playing

Dancy Ants is a live music visualizer that runs in your browser. It listens to the music in the room — the kick, the bass, the highs, the build — and the picture on your TV or projector moves with it. With Autopilot on, it changes when the drop lands.

There's nothing to install and nothing to connect. Open it on a laptop, send the picture to the big screen, press play on whatever you were going to play anyway.

How it works

Three steps, about a minute

1. Open it on your laptop

Go to dancyants.com in Chrome, Edge or Brave. No app, no download. Once it's open, it keeps working without internet.

2. Send the picture to the screen

Plug the TV or projector in with HDMI and press Send to Screen 2. On a Mac you can AirPlay to the TV instead; Chrome can Cast.

3. Play music

Anything the laptop can hear. Or let it listen to the laptop itself — a Spotify or YouTube tab, or (on Windows and recent Macs) any app — with Listen to this computer.

Play any music: a speaker beside a TV, the picture moving with every beat
Works with

Anything that makes sound

It listens instead of plugging in, so it doesn't care where the music comes from.

  • Spotify
  • Apple Music
  • YouTube
  • SoundCloud
  • Vinyl
  • CDJs
  • A USB stick
  • A DJ controller
  • A live band
  • An audio interface

The sound is analysed on your laptop and never leaves it — see the privacy page.

What's inside

Let it run, or play it yourself

Autopilot runs the visuals from the music on its own: it holds through the build and changes on the drop. Or take over — every part of it is a control.

Questions

Before you try it

Do I need to install anything?

No. It runs in the browser — Chrome, Edge or Brave on a laptop or desktop. Once it has loaded, it keeps working without internet.

Do I need an account?

No. Open it and play; the free version carries the Dancy Ants mark. A free account keeps your saved looks on every machine you use, and you need one to buy.

Does it work with Spotify?

Yes, and with anything else that plays sound. It listens through the microphone — or, with Listen to this computer, to the laptop itself: share the Spotify tab, or the whole screen with its sound. More in Spotify visualizer on your TV.

How do I get it on my TV?

A cable is the most reliable: HDMI from the laptop to the TV, then Send to Screen 2. Wireless works through AirPlay on a Mac or Cast in Chrome. Step by step, for every kind of TV: music visualizer for TV.

Can it run on the TV without a laptop?

Not today. There's no TV app — the TV shows what the laptop sends. A TV's apps can't listen to the room, so something in the room has to do the listening.

Does my audio leave my laptop?

No. The sound is analysed on your machine and never uploaded. It's only recorded if you press Record, and that file stays on your computer.

What does the free version look like?

The full instrument, with DANCY ANTS written across the picture and a small tag in the corner. $39, once, removes it.

Is it safe for people sensitive to flashing light?

The strobe is held to three flashes a second — the usual limit for people sensitive to flashing light — unless you switch that off. If you're showing visuals to other people, tell them there will be flashing lights — the terms say more.

What's the Commercial licence for?

Paid work: DJs, VJs, venues and events where someone is being paid for the night. It runs on three machines at once.
