As if computers weren’t complicated enough already.
A programmable 8-bit computer created using traditional embroidery techniques and materials
The Embroidered Computer by Irene Posch and Ebru Kurbak doesn’t look like what you might expect when you think of a computer. Instead, the work looks like an elegantly embroidered textile, complete with glass and magnetic beads and a meandering pattern of copper wire. The materials have conductive properties which are arranged in specific patterns to create electronic functions. Gold pieces on top of the magnetic beads flip depending on the program, switching sides as different signals are channeled through the embroidered work.
