Insa is one of the UK's most innovative and respected graffiti writers. He is probably best known for his Heels image in which he uses powerful black and white patterns to play with and distort spaces and to entice the viewer into the fantasy world of materialistic aspiration and in turn question contemporary consumer culture and commodity fetishism.
His high heel designs have featured on a number of INSA-styled products from ladies' underwear, toys, t-shirts, high-heeled shoes and custom designed sneaker. He established himself from a graffiti background through extensive street level work and gallery shows around the world. In 2010 Tate Britain commissioned him to produce a response to the recent Chris Ofili, exhibition that resulted in a very interesting pair of high heels featuring elephant dung.
