Digital murals are just as much subject to copyright law as any painting, even if they’re only pixels on a screen or a projector. The key point is that the work is a creative expression, so the original creator owns the rights. If someone re‑creates the mural in a different resolution or on a different medium, that can still be a derivative work that requires permission. Even when it’s displayed on a public wall, it’s a public performance of the image, so the venue must have a license. The trickiest part is figuring out who owns the digital file itself versus the display – the designer may own the file, while the venue owns the rights to project it. In short, a pixelated wall doesn’t remove the need for clear, documented permissions and licenses.

Sounds right to me. Keep the permissions tight and you’ll avoid a wall of red tape.

Nice, just keep the paperwork neat and let the creativity flow.
