*
* Toneclock. Peter Schat (1937-2003) was a Dutch composer. Het invented
* the toneclock, a garphical representation of the tonesystem.
*
* Revision History:
* 20-Dec-2004: Initial release
* 23-Dec-2004: -size determines size of the clock
* -original ignores all options and displays original clock
* -pulsate make the clock pulsating
* 24-Dec-2004: -fill num
* polygon filling chance implemented
* 04-Jan-2005: -move allow moving for small clocks
* 16-Feb-2005: -Number of hours according to "count" option
* -Random polygons
*
