The I Ching oracle is traditionally determined by using coins or yarrow sticks.
At no2DO.com we use a mix of human factor and computer generated random numbers: as long as you move the mouse within the playing field, the mouse movement’s x and y coordinates are added up; the longer you move the mouse, the greater the numerical value.
If you finally click the mouse a random number is generated and multiplied twice with the previously calculated sum of x and y coordinates. Subsequently, the respective next integer is determined (through eliminating decimal places) and, depending on whether it is odd or even, a solid (Yang) or a broken (Yin) line is drawn.
Thus, as long as the querist moves the mouse, he actively influences the numeric value. Just like with coins or yarrow sticks the result is determined by the querist – and no a “random number” as with most online oracles.
