3D print of a yield curve surface with change in material to create grid lines; on matching laser cut box with light inside. Left axis is time (2006-2010), right axis is "term structure", i.e. interest rates for 1 month out to 120 months; height at any given point is the interest rate on that day for that time period. Data is from Bank of Canada, visualization and print is is by Richard Brath at Uncharted Software.
