Afaik it hasn't. Therefore, I look at some colored, randomly placed smilies from to time time to elevate my mood:

function smilies(){ while true; do num=$(( $RANDOM % 80 )); for i in $(seq 1 $num); do echo -n " "; done; echo $(tput setaf $(( $num % 10 )) ) ; sleep 0.17; done }

XScreenSaver's closest equivalent is "rocks"; you might try something like this (unfortunately, when you ask for one color it's not white)

    rocks  -no-move -no-rotate -colors 1
