Stop what you're doing. Stereonet software now displays data in 3D, let's you rotate, go crazy. Geologists, get excited. Anyone who has worked with stereonets by hand knows that in addition to being an invaluable structural geology tool, they are also a pain, especially for large data sets. For the unfamiliar, stereonets are circular graphs that are used to represent 3-dimensional data in 2-dimensions. Data can be everything from bedding measurements, fault orientation, to cleavage planes in a fold. Once this data is plotted on the stereonet it can be manipulated to work out everything from the deformation history of a region to the correct orientation to drill a mineralization zone (ie. where's the gold at?). Figure 1: Some bedding plane and lineaion data displayed on a 2D stereonet in OSXStereonet. Stereonets are notoriously difficult for students to grasp on the first try around. My undergrad (UCSC) structure class used a hamster ball-cd set up to explain 3D bedding p...
