Peter Eisenman's Berlin/Holocaust memorial Light and Shadow. I like the way the structure of the building creates strong impressions of light and dark. Also the juxtaposition between the natural and man-made forces interests me.
Post Repetition of Form This image gives a sense of unity because of the actual wire pattern is a unified pattern. The added shadow cast by the wire adds an accenting unity to the entire piece, so it seems chaotic at first, but is actually unified.
This piece works with shadow art, which I find very interesting. I love pieces with crisp lines and the affect of the nails has exactly that. The contrast between the white wall, dark nails, and light shadows is dramatic, yet simple.
