GRAF80

One wall. Everyone paints on it. Nothing resets — your tag stays up for every visitor, just like a real wall.

• Draw — pick a can/brush, colour, size & flow, then drag on the wall.
• Hold the can on one spot (or scribble over it) and the paint pools and drips down. Fresh colours cover old ones.
• Zoom — mouse wheel, the +/− buttons, or pinch on mobile. Hide tiny details by zooming in.
• Move — two fingers on mobile, or hold Space / the PAN tool and drag.
• Snap — save a timestamped shot of the whole wall to the gallery.
• No eraser. No undo. Paint like you mean it.
