Calculates and displays biorhythm graphs.

Enter your birthdate and this Applet and it will calculate
your biorhythms for any day in the past or future.
It computes your 23-day physical, 28-day
emotional, 33-day intellectual and combined cycles. The
combined cycle is sometimes called the luck cycle. The
theory of biorhythms is when the cycles are positive/high
you will have high energy. When they are negative/low you
will have low energy. When they are zero or critical, you
will have unstable energy.

It can be run as a Java Applet or application.
