I have catalogued all the barriers that I have seen in the streets of London and those that are available to rent and buy from English sites.
So you have a complete view of the forms and types of barriers that there are.
Graphics are a very important element in these objects because they must be noticed in the street.
What would happen if we made it a camouflage? What if we put colors that you notice but are not among those used? For example, I could try using a fluorescent pink with cobalt blue. They would be visible but how would people react?
