Human evolution...past, present, future; layered like geological strata. I have literally walked on this piece, leaving my footprints in the different evolutionary eras...the fossilized mud of the past, the strip-mined landscape of the present, and the skies beyond the earth in the future. Colors progress from low frequency red in the past to higher frequency blue in the future, symbolizing hope for the continued advance of our best human qualities. Wire mesh, rather than canvas, is the substrate for this work. Its grid references the fabric of space-time that links the past to the present and future.
