After Karel is an audiovisual installation work inspired by the prints of Dutch artist and typographer Karel Martens. Martens' painstaking prints made using found objects are the essence of simplicity and commitment. In making a generative sound and motion graphics project inspired by his images, I am transferring the painstaking detail of the physical act of printmaking to the differently painstaking act of multimedia programming.
Unlike my usual approach to sound-and-image, in this series the sounds are directly determined by the images themselves: each ring represents a distinct voice within the choral totality of the sound, and the characteristics of each voice are directly mapped to the details of the ring: its outer and inner sizes, position on the "page," transparency, "ink," and color in terms of hue, saturation, and lightness as well as redness, greenness, and blueness all influence -- and in fact create -- the harmonic and dynamic components of the sound.
Below is a compressed and sequenced version of the piece; in an installation format each image and sound would persist far longer. This video represents a small selection of the compositions I've selected from those generated by the software.
Just as Marten's surfaces appear to be found papers (receipts, lists, notes...), the backgrounds on which these "virtual prints" appear are found digital artifacts. Various versions of the piece display the shapes on found film footage, books, charts, maps, and tables. In this case, the correspondence between the astronomical/astrological tables and the planetary ring-like shapes is a happy concordance.
