+ In many ways, the simpler and cleaner the better 
+ Avoid possible link to the &quot;green agenda&quot; 
+ Greenfield means &quot;without constraints&quot; 
+ Making simple out of complex 
+ Consider the concept of a bright, more attractive view on the outside (of a stuffy &quot;brownfield&quot; office) 
+ creativity and open space V inside, insular and dark/gloomy 
+ something abstact though 
+ change and evolution 
+ kaleidescope images - seeing things in a new way 
+ optical illusions 
+ lenses that improve clarity / perspectives 
+ new perspectives or new direction eg a new type of weather vane - a new &quot;3-D&quot; type (not 2-D like N,S, E W .....) 
+ &#39;outside-in&#39; thinking

We are delighted with the results, and very pleased with how quickly Blenk responded to our requests.  I would definitely recommend Blenk.  I would also add that the quality of all ideas was very high.
