YARN at Bolton's “Put Big Light On” Festival

Bolton Town Hall, Bolton

Creative studio Novak approached Graymatter Video to provide the technical design and system delivery for YARN, a stunning large-scale projection artwork set to illuminate Bolton’s iconic Town Hall in December 2024. Featuring original music by Ed Carter, YARN was conceived as a captivating audiovisual experience, transforming the Town Hall façade into a moving tapestry of vibrant colour, dynamic motion, and immersive sound.



The installation was commissioned as part of the “Put Big Light On” Festival, honouring Bolton’s rich journey from a modest rural market town to a pivotal force in the Industrial Revolution. Through vivid animations and powerful storytelling, YARN celebrated the town’s renowned mill production, visionary designers, historic landmarks, and modern role as Greater Manchester’s Town of Culture.

The Challenge: Tackling Scale and Complexity

The Town Hall’s vast façade (50m wide, 61m high), dark stone surface, and detailed architecture, including towering portico pillars and a prominent clock tower, posed major challenges. Achieving the creative vision required 150–180 LUX brightness, perfect projection across three building sides, and seamless integration of the staircase, all while avoiding shadows and maintaining flawless clarity.

The Solution: Precision-Delivered LED Technology

We delivered a robust system using ten Panasonic RQ35k and four RZ21k projectors, paired with our disguise GX 3 media servers and advanced 3D mapping to handle the complex structure. A network of Lightware HDMI fibre extenders and a 24 x 24 matrix ensured synchronised, high-bandwidth delivery. For audio, we installed a d&b Audio Y series line array, delivering Ed Carter’s score with immersive clarity. Five custom weatherproof towers secured the installation and provided optimal projection angles.


The result was a breathtaking fusion of light, sound, and storytelling. YARN captivated thousands of visitors, transforming Bolton Town Hall into a mesmerising visual and audio experience that celebrated the town’s industrial roots, cultural icons, and creative future. Our expert technical delivery ensured Novak’s artistic vision came to life, proving the power of collaboration between creativity and precision engineering.

In the world of filmmaking and content creation, it’s easy to get caught up in the debates: Is green screen outdated? Are LED volumes the only future? Will virtual production replace practical effects entirely? In this blog, iMAG’s Creative & Development Director Stephen Maddox explores why the smartest productions don’t choose between green screen or LED — they use both, blending tools to serve the story and deliver the best creative results. Filmmakers and content creators today face no shortage of strong opinions: “Green screen is dead.” “LED is the only way forward.” “Virtual production is replacing practical effects.” But these conversations often miss the point. Why It’s Not About Sides, It’s About Solutions At iMAG, we believe it’s not about choosing sides, it’s about choosing the right tools for the story you’re telling. On one of our recent projects, we used our LED volume for 90% of the shoot. But for the remaining 10%, we dropped in a green screen section precisely where the camera was aimed, allowing the post team the flexibility to dial in later the content yet captured. The rest of the volume still played plate content in-camera to light the scene authentically. On another project, we repurposed the LED wall to act as: A translite replacement for background depth, A green screen surface for keyed inserts, and A platform for in-camera VFX, all in one setup. By doing so, we avoided hauling in a truckload of fabric, lighting rigs, or set paint. In a third case, we simply built a green screen opposite the LED volume so the team could move seamlessly between both environments and maximise every shooting hour. It’s Not One Size Fits All: Adapting to Actors, Crews, and Environments Some actors dislike acting in an empty green box. Others get motion-sick in an LED volume with Ghost Frame or Frame Remapping. Some crews are experts at traditional compositing, while others thrive in Unreal Engine environments. These are not reasons to reject one technology over another. They’re reasons to plan smarter, and mix methods intentionally. Filmmaking isn’t about forcing every scene through the same process—it’s about staying agile, creative, and technically aware. In The West Wing, President Bartlet once said, “The trick isn't picking the right lever… It's using all of them.” The same applies to production. It’s not a matter of green screen or LED or pick your production process. The best work comes when we approach each scene with a full toolkit and the wisdom to know which lever to pull. At iMAG, we see green screen, LED volumes, virtual environments, practical sets, and physical builds as complementary, not competing. Wouldn’t you want to go into your next project with a full toolbox instead of empty-handed? Final Thought: Ask the Better Question The real question isn’t, “Which tool is best?” (My favourite question from The Office, “Which bear is best?”) The better question: What does this story need? What does this moment demand? How do we bring it to life—visually, emotionally, and efficiently? When we stop picking sides and start picking solutions, the work gets better. And that’s what matters most.
