sometimes, the 30Hz "signal" transmitted to the user by the simple fact
that the text is rapidly changing is actually very useful. 30fps is
roughly the level needed to avoid visual perception of discontinuity -
one could argue that 10Hz or 40Hz might be better for a visual "image"
that isn't ever going to be continuous anyway. either way, its not clear
to me that changing text so fast that it cannot be read is WRONG. there
are certainly many cases where its counter productive.
