Click on the numbers to drag the control poses
'h' to reset the control poses
'L' to load saved control poses
'c' to show/hide the control poses
'p' to show/hide the path of the ball-center
'a' to toggle animation / stroboscopic view
's' for single circular motion between each pair of consecutive control frames (C0)
'f' for a four-point subdivision (C1)
'j' for jarek subdivision (C2)
'b' for a cubic B-spline subdivision (C2)
'm' for mixed subdivision (C4)
