Designed by the sister duo Sarah and Lara Grant , Fortune Teller is a novel interface designed to work with the Arduino controller and Max/Msp. It is constructed from hand-made conductive felt made from a combination of steel wool and non-conductive wool fibers using dry felting techniques.

Carding of wool fibers
I absolutely LOVE the documentation of the felting process particularly the manual process of carding together of the wool fibers and the needle-felting of the conductive fibers. The Fortune Teller uses the differences in resistance of the conductive felt to create a range of values which is communicated to the Arduino to control an output.
