2D Riemann Sum of f(x, y) = sin(xy)
This piece is an illustration of the function sin(xy), created using a sculptural technique inspired by Riemann sums, a kind of approximation. Based on plans generated by a Python script, square acrylic rod was cut to precise lengths in 1 mm increments using a model railroad tie chopper, then dyed using alcohol ink blends carefully formulated to give the sculpture an "inner glow" when viewed under ambient light. After dyeing, the rods were hammered into a 3D-printed base using a rubber mallet.
