    This is awesome software. It allows you to go on Spherical Geometry adventures without getting your hands dirty on a perspex sphere. You can use it for a lot of applications, but sadly measuring angles are not supported. Obviously ways exist to do just that, but it takes about 10 minutes just to measure one angle... What's the best about this software is the ability to showcase your sphere and your findings on a projector to the whole classroom. Also you can drag around points on the sphere. For instance when you create a Great Circle, you can move the pole point around to show the class different scenarios. Great software! Only lacks the angle measurement and the ability to make coffee for the developer which truly deserves this!
