I am not sure what to call this type of art, but it must be getting a name soon...it is where artists use all types of unusual materials to bring out the basic highlights of a picture into a work of art. This one uses push pins. I will enclose serval for you to view. At first I was totally amazed with some of these, then no matter how interesting, there was a tricky feeling, a little bit slick or something. So I don't know exactly where I land on my artist feeling about these, but I still do find them interesting. And one cannot deny the artist have talent.
