Artist Warren Elsmore said: "My job is playing with Lego bricks every day, I've loved it since I was a kid and it's just that challenge - the bricks fit together in a certain way but there's also no limits, you can literally build anything out of Lego, and that I really like."Image source, Martin BarberImage caption, All of the models have been designed by Warren and his team. "There's some really tough challenges about building Lego models to this size, we need to have special frameworks in them and we have to be careful how we sort of sculpt with the bricks to make sure they look natural and really lifelike," said Mr Elsmore.Image source, Martin BarberImage caption, The show also features a model of Dippy, the Natural History Museum's famous dinosaur that has been touring the UK.
