In Zip Stack Flow, Grassi creates paintings that appear to be compressions of her painting process—much like zip files or stacks—tightly packed with bits of data and time. In data visualization, “stacks” of information are mapped out into quantifiable values that result in graphic images that can be aesthetically captivating. Zip Stack Flow references not only the formal properties evident in Grassi’s paintings but also the language around technology and the nature of work.
