These are some photos from a project undertaken last year. I had to construct large polystyrene boulders to use for set dressing in the Natural History Museum's "T Rex Killer Question" exhibiton staged at Birmingham's Gas Hall Gallery. The boulders were sculpted by hand out of large, 8 foot tall blocks of poly, then painted and used within the various animatronic scenes to blend in with backgrounds and hide pipework, lighting etc.
