/*------------ HAT - (SELF-CONTAINED FUNCTION) ------------*/
// Hat is created from a torus, a cylinder and a disk. 
// Origin is at the bottom of the hat 
// to be able to place it on a head or a surface.
// Radius of hat 1.4, height 2.
// Color needs to be set by the user beforehand with twColor(). 
// Suggested values: 0.5 for specularity and 100 for shininess. */
void hat(); 


/*------------ CLUB - (SELF-CONTAINED FUNCTION) ------------*/
// The club has a total height 7.5.
// Origin is at handle and the club points downwards.
// Color needs to be set by user beforehand with twColor(). 
// Suggested values: 1 for specularity and 30 for shininess.
void club(); 


/*------------ BEANBAG - (SELF-CONTAINED FUNCTION) ------------*/
// Beanbag is a striped juggling ball. 
// To make the ball striped two spheres are placed into each other:
// one is stretched along the x-axis while the other one along the z-axis. 
// This is how the illusion of the stripes is created.
// Origin is at the bottom of the ball, radius of ball is 1.
// Beanbag has two colors one is always black.
// The other one is determined by the user with the twColor() function 
// before the beanbag function is called.
// Suggested values: 1 for specularity and 40 for shininess.
void beanbag(); 


/*------------ SPIRAL - (SELF-CONTAINED FUNCTION) ------------*/
// This function draws a spiral.
// One spiral has length 4.
// It takes 3 arguments:
// 1: color
// 2: int n - the number of spirals put together
// 3: int nsteps - how many steps it takes to draw the curve 
//    (efficiency vs smoothness)
// Light behaves a little strange with this bezier curve.
// Origin is at the bottom of the spiral.
// And the spiral advances along the +y-axis.
void drawSpiral(twTriple color, int n, int nsteps);
