So this is what I have been helping Kyle Bean with recently – his most ambitious project yet, and the result of a successful pitch to Selfridges. Kyle had to come up with an idea to fill their five ‘wonder windows’ just off their frontage on Oxford Street over the summer. My role was to help with the design and construction of a castle made from the pages of fairytale books. All the mountboard used had to be covered both sides in the book pages, and different sized lolly stick tips came in handy as templates for the many windows.

When I was at work in Kyle’s studio, he would often be on the phone or chatting online about the rest of the displays he was art directing, so it is extra interesting to be able to see how they turned out. The whole idea is based around the law of conservation of mass – ‘Matter cannot be created or destroyed, only transformed’ – so in each window you have a pair of giant scales showing the balance in the two stages of transformation from constituents to product. If you are about London in the next two months, go and take a look.
