yep great song. I'm always interested in the meaning behind songs that i like, especially with artists who have strong political views like RATM or SOAD. Anyways I looked up Lateralus on Wikipedia a few weeks ago and thought this was really clever and interesting:

On the ninth track of the album, "Lateralus", Keenan's vocals during the verses coincide with the Fibonacci sequence (1,2,3,5,8,13,4,6,7,9,10,11,12) by syllable. The number of syllables progress to the sixth step, then back down to the first step; up to the seventh step, and then back to the fourth step:
[1] black
[1] then
[2] white are
[3] all I see
[5] in my infancy
[8] red and yellow then came to be
[5] reaching out to me
[3] lets me see
[2] there is
[1] so
[1] much
[2] more and
[3] beckons me
[5] to look through to these
[8] infinite possibilities
[13] as below so above and beyond I imagine
[8] drawn outside the lines of reason
[5] push the envelope
[3] watch it bend
