Just click the green flag and watch. You may want to shift-click it. The equations for the Halvorsen attractor are: dx/dt = -ax - 4y - 4z - y² dy/dt = -ay - 4z - 4x - z² dz/dt = -az - 4x - 4y - x² Here, a = 1.89. The thumbnail's orientation is (X,Z). Press O to change the orientation. Orientation 1 (X,Y) displays the X value as the X value and the Y value as the Y value (it can't be any simpler) and is the standard orientation. Orientation 2 (X,Z) has the Y value corresponding to the Z value. Orientation 3 (Y,Z) has the X value corresponding to the Y value and the Y value corresponding to the Z value. Basically, it's three viewpoints to look at the attractor from.
