Paint the invisible. Leave your mark on walls that only ghosts can see.
GhostCanvas is an AR app that lets people leave collaborative digital murals on real-world walls. When someone paints a ghost mural, others discover it and can add their own contributions — creating massive, elephant-scale community artworks that turn urban spaces into living galleries without physical paint.
You point your phone at a blank alley wall and suddenly see hundreds of translucent ghost figures painted by strangers. You add your own brushstroke, watching it blend into a massive collective artwork — feeling simultaneously alone yet connected to everyone who's ever stood right here.
