Don't feel bad, I looked at Jim's message and said, "no that's wrong!"  
Then after thinking about it for a few seconds I figured out that what I 
was thinking of was the patterns of 0x55 and 0xAA being (in binary) 
01010101 and 10101010 respectfully.  I use those often in uC work when 
trying to watch serial data on a scope with no decode.
