Appearing in the fourth episode of the current series of Dragons’ Den on BBC2, Tom Hogan and Tim Williams impressed the Dragons with their unique digital graffiti wall called YrWall (pronounced 'your wall'). After an impressive demonstration of the technology the pair were successful in securing £50,000 – the entire amount they sought from the Den – for 40% of the business. Deborah Meaden and Peter Jones both made tempting offers to the entrepreneurs and, unable to decide between each offer, Tim and Tom asked the Dragons if they would both consider investing. A move that proved fruitful for the entrepreneurs as the Dragons agreed, investing £25,000 for 20% of the company each.

YrWall is an interactive and inventive drawing tool for creating digital graffiti on a large screen using a modified spray paint can. Instead of paint, the can ‘sprays’ infrared light which is tracked by a computer vision system as it moves across the screen. The digital paint appears wherever the can is sprayed, just like graffiti on a real wall. Creations can then be saved, recalled and played back, as well as used to create a variety of unique and personal mementos of the digital graffiti experience, such as T-shirts, stickers and postcards, which can then be taken away.

Lumacoustics, the parent company behind YrWall was set up by school friends Tim Williams and Tom Hogan in 2009. Since then, the digital graffiti wall has proved hugely popular at gigs and exhibitions, and also at corporate and consumer events for an impressive list of clients including Google, MTV, NatWest, Orange and Chevrolet. Lumacoustics and their new Dragon investors believe there is massive potential for the technology to be applied in other markets, such as gaming and the high street leisure sector, which is constantly searching for non-gambling methods of amusing their customers.

Tim Williams, Lumacoustics, said: “Demand for YrWall is growing, particularly amongst the event market but with the expertise of ‘Dragons’ Deborah Meaden and Peter Jones, we can take our technology and ideas to the mass market. An incredibly exciting time for the company, even though securing the funding on ‘Dragons’ Den’ was one of the most terrifying experiences of our lives!”

Investor Deborah Meaden said: “Once I tried using YrWall myself I realised what a fun and inventive product it was, with strong potential for a wide variety of applications and different markets”.

Peter Jones added, “I was really impressed with the technology used in YrWall and I'm looking forward to working with Tim and Tom, and also with Deborah, to develop it further and make the business a success”.
