Sime's brightly-colored sculptural tableaus feature found objects including thread, buttons, electrical wires, and computer detritus. This book highlights the artist's work from the last decade, much of which comprises the series entitled "Tightrope." Repurposing salvaged electronic components, such as circuits and keyboards, Sime incorporates the refuse that are the byproducts of technological advancement, and points to the urgency of sustainability. The resulting abstractions reference landscape and the figure as well as traditional Ethiopian textiles. "Tightrope" refers to the precarious balance between the progress technology has made possible and its detrimental impact on the environment.
