This program displays a sphere undergoing the Thurston eversion.
To rotate, click and drag with the left mouse button.

MOUSE ACTIONS (buttons 1-3)
  
  object window          : Rotate the deformed sphere by dragging horizontally.
  panel window           : Adjust parameters
  WM check cross         : Quit program

KEYBOARD ACTIONS
  F1              : Toggle eversion
  F2              : Toggle rotation
  F3/F4           : Increase/decrease number of latitudinal patches
  F5/F6           : Increase/decrease number of longitudinal patches
  F7              : Reset number of patches to default (48)
  F8              : Toggle command panel
  space           : Pause / restart animation
  - , +           : Decrease, increase time t by time step delta_t.
                    This provides an alternative way of everting
                    the sphere, instead of pressing space.
  * , /           : Multiply,divide time step delta_t by 2.
                    This changes the speed at which the eversion is performed.
  tab &           : Cycle through polygons/checkered polygons/bands/points
  s               : Toggle smooth/flat shading
  b               : Toggle backface culling
  f               : Toggle which faces are front facing
  r               : Cycle through rotation modes
  c               : Cycle through color channels
                        front face & back faces (/)
                        front face (0), back face (1)
                        background (2), text(3), panel(4)
  page up/down    : Increase/decrease total number of strips
  right/left arr. : Increase/decrease number of strips displayed
  up/down arrows  : Zoom in/out
  end             : Toggle display of lower hemisphere
  home            : Toggle display of half-strips
  1-8             : Select predefined colors
  0               : Darker color
