Anna Craycroft is writing A Weekly Correspondence in conjunction with her exhibition C’mon Language currently on view at Portland Institute for Contemporary Art, June-September 2013. In each installment Craycroft integrates influences from her research with ideas presented by the different contributors to the exhibition. In this Correspondence #6 Craycroft relates Froebel’s cosmos to Lucy Raven‘s workshop on the visual music of Oskar Fishchinger.
