In each of these images, the clipped object in the forground sits in a scene that is otherwise completely computer rendered using C++, global illumination techniques, and principals of fractal geometry.
Each of the clipped objects was originally rendered by hand a few hundred years ago (with the exception of Seurat who finished painting "A Sunday on La Grande Jatte" in 1886).  
Placing such iconic objects with such a rich and storied provenance into scenes generated through the use of modern technology creates a pathway through history that links us all to the past and makes our present and future rich, hopeful, and meaningful.
