Goldberg began the Metagraph series in 1999, drawing in Adobe Illustrator with a tablet. These are vector drawings: their lines and shapes are described mathematically, allowing an image to be rendered at different scales. The name Metagraph refers to this underlying description of the image, which can exist in more than one physical or digital form. Gesture and automatic drawing give the compositions their expressive character. Physical prints and editions are recorded separately from the digital originals. Beginning in 2021, Goldberg extended selected drawings into animations with sound. These moving versions also appear in augmented reality and in the Metagraphs book.

Begun in 2004, the Wireframe series developed from Goldberg’s Metagraph digital drawings. Gestural lines were rotated in three-dimensional space to form structures that recall architectural and engineering drawings. Printed onto painted surfaces, these digital structures meet the textures and gestures of acrylic, oil and ink on canvas or linen. This exchange between digital construction and physical painting helped shape the approach Goldberg named Techspressionism in 2011. For Motion Paintings, generative tools were used to animate images of selected finished paintings, extending their lines, forms and surfaces through time. The painted work provides the starting image for its moving counterpart. Scan the QR code specific to a painting with a mobile device to open the animation in the mobile browser.

The Wireframe series began in 2004 as a development of Goldberg’s Metagraph digital drawings. Rotating gestural lines in three-dimensional space produced structures reminiscent of architectural and engineering drawings. In the works on paper, these digital structures combine with painted and printed surfaces, bringing precise line work into contact with the textures of ink, paint and paper. This movement between digital and physical processes helped shape the approach Goldberg named Techspressionism in 2011. Generative tools were subsequently used to set images of selected finished works into motion, giving their existing lines, forms and surfaces a time-based expression.
