# Interactive Digital Graffiti Wall > A wall visitors paint on with motion-tracked spray cans or touch -- strokes, drips and colour appear live, and each finished piece leaves with the visitor. An interactive digital graffiti wall lets visitors paint onto a large screen or projection using a tracked spray can, a stylus or their hands. Strokes appear live with drip and colour behaviour, the canvas can be branded, and each finished piece is captured so the visitor takes something away. MLABART delivered one for Hisense at Hudson Yards, New York, in June 2026. ## What MLABART delivers - Interaction software: stroke rendering, colour and nozzle behaviour, canvas reset and session handling - Branded canvas content -- line-art backdrops, brand elements, seasonal or campaign artwork - Tracking setup for spray cans, hands or touch, calibrated to the actual wall and lighting - Capture and output: each finished piece saved as an image for the visitor - System integration, factory testing, on-site installation, commissioning and show-period support ## Typical scenarios - Brand pop-ups where visitors need something to do, not just something to look at - Trade show booths that need to hold a crowd without one-by-one queueing - Product launches where the canvas carries the campaign artwork - Music, sport and culture events with a young audience - Employee and dealer events where a collective mural builds over the day ## Delivery model Reusable product -- a proven configuration that deploys quickly and can run in several cities in parallel. ## Venue and site requirements - Wall or screen surface from roughly 3 m wide; larger walls support more simultaneous painters - LED display for daylight and high-ambient-light venues; projection only where light is controlled - Clear standing depth in front of the wall for painters plus onlookers - Standard mains power; network only if artwork is delivered to visitors digitally on site - Outdoor use needs a plan for tracking-hardware temperature and weather protection ## Included as standard - Interaction software and stroke engine - One branded canvas design - Tracking hardware and on-site calibration - Artwork capture and digital handoff to the visitor - Factory testing before shipping, on-site installation and commissioning ## Available as an option - On-site photo printing of the finished artwork - Printing artwork onto T-shirts or other merchandise - Collaborative mode -- one shared canvas that many visitors build over the event - Additional canvas designs for multi-day or multi-city runs - Leaderboard, gallery screen or social handoff - On-site technical staff for the full show period ## How it works - ![Visitor flow at an interactive graffiti wall: walk up with no sign-up, pick a colour, paint with strokes appearing live including spread, drip and overlay, confirm so the piece is captured, then take it away as a digital image, a printed photo, a printed T-shirt, or a contribution to a shared mural that is never reset. Digital takeaway adds no session time and gives the highest throughput; T-shirt printing needs a press, blanks in sizes and trained staff and gives the lowest.](https://mlabart.com/insights/graffiti-wall-visitor-flow.svg) -- A session at the wall usually runs 60-120 seconds. The output format is what adds to that -- and what decides how many visitors you get through in a day. - ![Five-stage mechanism of an interactive digital graffiti wall: tracked spray can, hand or touch input; position and trigger sensing; a stroke engine handling spread, drip, colour and nozzle behaviour; a branded LED or projected canvas; and output to the visitor. Display type follows venue light rather than preference, and the output format decides footprint, consumables and staffing.](https://mlabart.com/insights/graffiti-wall-how-it-works.svg) -- Two of the five stages are decisions: the display type (set by venue light) and the output format (set by what you want guests to leave with). ## FAQ ### Can guests take their artwork away? Yes. Every finished piece is captured as an image and handed to the visitor -- that was the configuration MLABART ran for Hisense in New York. On-site photo printing and printing onto T-shirts are available as options and are quoted per project; they need extra footprint, consumables and an operator, so they are decided at planning stage rather than added on site. ### Screen or projection -- which is better? LED screens hold up in daylight and high ambient light, which is why an outdoor or daylit venue usually needs one. Projection covers a larger surface for less budget but needs controlled light and clear throw distance. The venue decides this, not preference -- MLABART surveys the space before specifying. ### How many people can use it at once? Typically two to four simultaneous painters on a standard wall, depending on width and tracking method. Throughput is set by session length rather than the hardware: shorter sessions move more visitors, longer sessions produce better artwork. We set the session length against your expected footfall. ### Does it need staff? Yes, we recommend it. In the Hisense New York run the wall was staffed throughout: visitors painted freely but floor staff guided each session. In a free public venue that is what keeps throughput predictable and the wall in a usable state for the next visitor. ### Can the canvas be branded? Yes -- the canvas is content, so it can carry line-art backdrops, campaign artwork, product silhouettes or a city skyline that fills in as the day goes on. Branding the canvas is usually what makes the output worth sharing rather than generic. ### Can it run outdoors for several days? Yes, with planning. Daylight legibility drives the display choice, and tracking hardware has to be sited so its operating temperature stays controlled -- heat is what makes sensors drift or shut down. The Hisense wall ran outdoors for a seven-day public run with zero failures. ## Related Pages **See also:** [Hisense - RGB Pop-Up, New York -- Four Interactive Installations Delivered from China](https://mlabart.com/work/hisense-rgb-popup-new-york/) --- **MLABART** -- Interaction - Imagination - Innovation MLABART is a creative technology studio specializing in interactive installations, digital multimedia art, and immersive experiences.
