Today is Ash Wednesday!
This piece by Marxhausen commemorates Lent.
I was curious if there were 40 colored pieces, but the number was well over that.
Its dark background may have been chosen because the color black is used to symbolize Christ's death on Good Friday. I see a cross-shape created by the rubber band stretched across the brightly colored pins. Prof. Anschutz recalled that Marxhausen made this cross lop-sided, and the rubber bands essentially submit to gravity and sag, representing the sin that made Christ's sacrifice a necessity.
