In moments that would have pleased Belgian surrealist RenĂ© Magritte, an ordinary paint roller transforms a litany of European landmarks with video “paint.” Roll on, and it’s as though someone has punched a hole to another dimension. This isn’t a post-production effect: it’s all live, via computer vision and projection mapping.

The project is the latest work by international duo SWEATSHOPPE. We’ve seen them twice before:
Painting with Video: Live Projected Wheatpaste with SWEATSHOPPE
Hypnotic Colored Geometries and Balloon AV from SWEATSHOPPE

SWEATSHOPPE’s Blake Shaw tells CDM:

Just writing you to send our new video painting video which shows us video painting in London, Paris, Berlin, Belgrade, and Bristol. Since the last video we extended the software so that we can paint layers of video, allowing us to create live video collages. We even created a 5 meter telescopic IR paint roller so that we could do a two story tall video painting in Bristol.

New media art duo SWEATSHOPPE aka Blake Shaw and Bruno Levy are back from Europe with a new video that showcases their live interactive video wheatpaste in Berlin, Bristol, Belgrade, London and Paris. Over a two week period the duo pasted their videos in over 10 spots including the Berlin Wall, Les Invalides, Cordy House and even constructed a 5 meter telescopic electronic paint roller to create a two-story tall video painting in Bristol.

Video painting is a technology the duo developed that allows them to create the illusion that they are painting videos onto walls with electronic paint rollers they built. It works through custom software that they wrote that tracks the position of the paint rollers and projects video wherever they choose to paint, allowing them to explore the relationship between video, mark making and architecture and create live video collages in real time.
