Isaac Cordal makes little people out of concrete and them places them in thought-provoking situations in various cities and countries in Europe. You can find them in the street, sitting on rooftops, precariously balanced on a pipe, standing up to their waists in water with a life preserver, or standing in the snow. The figures are made in clay, then a silicone mold is made in which the concrete is cast. Some of the figures are painted some left grey.
Some of Cordal's work is mechanized, but I particularly like the small quiet figures.
Street Art London
also has an excellent interview with Cordal along with other photographs of his work. A new book has also just been published about Cordal's work called Cement Eclipses, available from Carpet Bombing Culture
