Choose the light on your screen. This phone controller pairs with the Shaderfun display and gives you a gallery of thirty animated artworks.

## Connect

Open Shaderfun on your RCWeb screen and scan its QR code. Your phone and display need the same room. The status changes to **Display connected** when the controls are ready. Several phones can share the controls.

## Choose and customise

- Tap any artwork to display it. Scroll through the gallery to explore all thirty. The selected artwork is marked **Playing**.
- Tick the **top-right checkbox** inside each thumbnail to choose the continuous-play selection. Keep at least one selected; **Include all** restores the whole collection. Selections are saved and shared with other phones. Tapping a thumbnail still plays any artwork immediately without changing your loop.
- Use **Pause** to hold the animation and rotation timer. **Next** advances to the next selected artwork in gallery order.
- Adjust **Motion**, **Brightness** and **Colour shift** to suit your space.
- Enable **Automatic rotation** and choose how long to spend in each world. Disable it to stay with one artwork.
- Choose **Adaptive**, **Low power** or **High detail** quality for the display.
- Hide the title or QR invitation, or move the invitation to another corner.

Gallery thumbnails animate where your phone supports WebGL; only the cards on screen animate to save phone resources. Still previews remain available otherwise. The display saves your preferences for the current room. Fullscreen is activated using the icon on the display itself.

Use **Back to apps** to return this phone to the RCWeb app list. The artwork keeps playing until you choose another app.
