This is ‘pretend’ carpet. See where the floor board colour changes slightly?
They have photographed the carpet which is too fragile to be walked on and made a replica from a rubbery kind of product. It feels remarkably like carpet and you couldn’t tell to look at it but it gives a very realistic experience while preserving the real thing. Clever!
Lastly the tricks of landscaping. A facade in the distance gives a focal point and depth to the scene. Hmmm, Gilbert, do you think we could do this at home?
