Artist Lucas Maassen never had a sister. His parents separated before making another baby, so he did what any scientifically-inclined artist would do: he crystalized bits of his parents’ DNA. He then made larger copies of the crystals and had his parents assemble a sculpture from those crystals as part of an exhibition titled Confrontations. There’s something personal and endearing about his mission to personify his sister that was never born, but there’s also something strange and chilling about his experiment to materialize her. He explains the project here. For interested folks, there’s a longer video here that overlays his parents talking about their relationship and scientists describing the chemical structures and processes enabling the project.
