**Control Panel Options**

These options may be accessed from the panel to the left of the screen.

**Spheres** :: Number of spheres in the pattern

**Direction** :: Clockwise/Counter-clockwise

**Interval** :: Time between iterations

**Increment** :: Movement length per iteration

**Radius** :: Size of the pattern

**Alpha,Beta,Gamma,Delta** :: Secondary variables within specific formulae.

**Available Math Functions**

These may be inserted into the formulae at the top of the screen. Note the following:

- everything is there for a reason

- functions are Case Sensitive

- every ( must have a corresponding )

- feel free to play with +,-,*,/ in the input areas

- press [DIY] to see what you have accomplished
