A small cup-like form derived from 150 years of Sydney temperature data. Treating the form as a stack of rings, each ring represents one year's temperature, with the months arranged radially. The higher the temperature, the further the surface is from the center. Rings are stacked from bottom to top: at the bottom of this form is data from 1859 - at the top, 2009.
Data points are smoothed using a moving average with a five-year span, in order to make the form printable. The data is sourced from the UK Met Office HadCrut3 subset.
The form was generated in Processing, cleaned up in Meshlab and printed by Shapeways in their "Strong White Flexible" material.
