Wizuale

The picture fills the TV.

Two apps

Apple TV

Wizuale

Classic Milkdrop presets, the same kind Winamp used, full screen.

Coming soon

iPhone

Wizuale Mic

A separate app on the same Wi-Fi. The picture follows the sound in the room.

No account.

A bright yellow and black Milkdrop preset, full screen.
Open it, and a preset takes the whole screen. A few of them are here, including some from Study of Space.

Two separate apps

One lives on the television. The other lives on the phone. They meet only on your Wi-Fi.

Apple TV

Wizuale

Put on a record, or play music on the TV. The preset fills the screen. Move to another one with the remote, or let the next one come on by itself.

iPhone

Wizuale Mic

Connected to Apple TV

A second app. On the same Wi-Fi it finds the television and shows that connection on the phone. It sends the sound in the room, so the visuals react to what you hear. Pick a preset there, or leave them to advance.

Full screen

The visual is the television. Once it is playing, that is the whole picture.

The sound in the room

Connect the iPhone app. From then on, the picture reacts to what the phone hears.

BPM, then the beat

The Apple TV looks up the song and takes its BPM from GetSongBPM, so the picture has a tempo even with no microphone. Connect Wizuale Mic on the same Wi-Fi and the image bounces to the beat it hears in the room.

Pick a preset

Choose one on the phone and the TV stays with it. Or step through them from the remote.

Auto-advance

Leave it on and the preset changes by itself. Pick one when you want the picture to stay.

Put the music on.
Let the room move the picture.
