This is the third part of a tutorial (1, 2, self) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003. This section charts the pseudo random series after converting it from binary 14-bit numbers into decimal numbers scaled within the interval [0,1). A correlation chart is then created, displaying the first half of the series function of the second half, with a small adjustable offset (between -200, and 200). Two simple macros are used, one for the manual offset adjustment and one for the animated offset adjustment. Changing the offset (either manually or using the animated macro) one can notice various not-so-random patterns for certain offset values.
