Canadian-born artist, Angela Bulloch (b. 1966) studied in London, and has been grouped as part of the 'Young British Artists' (YBA) since graduating from Goldsmiths College in 1988. With an interest in working across multiple media, Bulloch creates pieces that explore the relationship between the real and virtual space in which her sculptures are designed. Now based in Berlin, she is known for colorful works that merge mathematics with aesthetics and encourage audience interaction.

Comprised of 6 vertically stacked rhombi painted in hues of blue, Heavy Metal Stack of Six: Trichrome Blue (2016) comes from a series of columns which exemplify Bulloch's strategy of combining a minimalist approach to science and math with a maximalist expression (Sculpture Milwaukee, 2019). To create these powder coated steel surfaces, Bulloch first utilizes digital imaging.

At first I conceive of them within the virtually real place inside a computer using 3D drawing programs. It's easy to play around with forms inside a space like that right up until you try to actually make them… [then] the simple 3D drawings are converted into engineering files which have to be very precise and self-sustaining. The sculptures eventually have to stand up in the real world under conditions of gravity, so the drawings often need some adjustments at this point-a reality check of sorts. Then the material is cut and puzzled together, the surfaces are treated in many different ways, the base plate (the means of attachment to the ground) is considered and chosen appropriately for the environment where it will end up.

Digital imaging allows the design of each rhombus to feel unique while also connected to its fellow column-mates, with the light and dark colors creating the optical illusion of shifting planes. Bulloch's work addresses the patterns, rules, and systems that order our lives and how mistakes or anomalies immediately stand out to the viewer. As the viewer walks around the column, the appearance of the sculpture shifts: one perspective highlights irregularities, while another presents a more regular totemic work. With these details in mind, Bulloch creates every piece with the intention of leaving interpretation entirely up to the viewer.
