The word yes is printed to screen. User votes 'yes', 'no', or 'maybe'. For each 'maybe' the word gets x amount bigger & more opaque. For each 'yes' it gets twice that amount bigger. Each 'no' is counted as zero and does not affect the size. It starts out sufficiently small that the first voters will not know what they are voting on unless the look at the page source.
