Vortexia can hold a sleep stream for the whole night with a slow, drifting picture. The look on this page is the Julia set, Neural Drift in the dashboard and one of the free engines, and it moves on its own even when nothing is playing, so silence does not freeze it. With quiet ambient music it moves gently; lower Audio Sensitivity so a sudden sound does not jolt it. The picture is bright by default, so for a darker room add OBS’s Color Correction filter to the source and lower its Brightness or Opacity; lowering Saturation there also calms the colours, which sweep round the whole wheel about every 20 seconds. It runs for as long as OBS does. The dashboard does the listening, so keep it open if you want the picture to follow the sound; closed, the OBS source keeps drifting and simply stops reacting.
How to use A Background That Drifts All Night
Add it to OBS. Copy your OBS link from the Vortexia dashboard and add it as a Browser Source.
Pick a calm look. Choose the Neural Drift engine.
Dim it. Add a Color Correction filter to the source and lower Brightness.
Soften the response. Lower Audio Sensitivity so sounds move it gently.

Frequently asked questions
Does it need music to move?
No. The picture drifts on its own. With music playing it also moves with the sound; lower Audio Sensitivity for a calmer response.
How do I make it darker?
Right-click the source in OBS, choose Filters, add Color Correction and lower Brightness or Opacity. Lower Saturation there too if the changing colours are too lively.
Will it run all night?
Yes. It is rendered live by the OBS Browser Source, so it runs for as long as OBS does. The free plan renders at 720p, which keeps it light.
What if I close the dashboard?
The OBS source keeps drifting; it just stops reacting to sound, because the dashboard is what listens.
Is it free?
Yes. The free plan streams at 720p and 30fps with a small watermark, three engines and Twitch. Plus removes the watermark, renders at 1080p and 60fps, unlocks all eight engines and adds automatic YouTube and Kick events.
