The image below is  a black & white sketch of an imaginary spacial construct designed and drawn by Jeffrey Michael George, Architectural Illustrator.  This illustration is one I have done for my own amusement, and hopefully for the interest of others.  The idea of this exercise was to use my imagination and my sketchbook to envision and render freeform objects set in space, with interwoven 3D relationship to each other.  Jeffrey provides many illustrations for architects in San Francisco, San Jose and South Bay, Bay Area Peninsula, East Bay, Sacramento, and Sierra Foothills of Northern California, bringing their designs to life in the form of architectural renderings.
