The maths in an election is quite simple but produces the possibilty for complex changes.  This quilt was made around the time of the Obama election victory.Those 'voting papers' beads represent the 'ones' from binary code, the small change pennies denote the zeroes. On each layer I allowed the grids to be a little uneven - change is never easy to co-ordinate. The blue and red strips can be woven to create a changing display on the quilt top, reminiscent of the changing electoral maps. My blog post sets out more background and construction details
