Prototyping proving profitable

A good workshop back in April in the North West and just found this image on iphone highlighting the prototyping of a new service for a major high street outlet.  Is that an upside down coat stand?  Course it is.  Materials to hand were very effective in this instance.  The simplest things are often the best. Quick, low cost concept development with the potential to transform the client company and open up their marketplace significantly to new customers.
