It's called a Linear Feedback Shift Register (LFSR) and is pretty
standard. 

Check this http://www.ece.cmu.edu/~koopman/lfsr/ web site for values
generating maximum length sequences.

Nice, and works with Opera too. :-)

Acutally, for maximum length terms, the seed is quite irrelevant,
because it only defines where the sequence should start. Any value
!= 0 works. An 8 bit LFSR should repeat after 255 iterations.

IIRC correctly, Glenn posted a nice demo here a few years ago.

Have fun!
