Some fun for your terminal!
Launch the following ./zmatrix script (after doing a chmod +x ./zmatrix) to be part of the ZMatrix 
Demo:
Code:
#!/bin/zsh
#based on http://codegolf.stackexchange.com/a/17337
COL=$(tput cols)
ROW=$(tput lines)
GREEN=`tput setaf 7`
WHITE=`tput setaf 2`
cleanup() {
printf '\033[2J\033[1;1H\033[?25h\033[0;0m' && tput sgr0 && tput cnorm
}
drop() {
for ((r=1; r<$2+$3+1; r++)); do
R=$RANDOM
CHAR=`printf %04X $((377+R%6))`
[ $r -lt $2 ] && echo "\033[$r;$1H$GREEN\u$(printf %04X $((377+RANDOM%6)))"
[ $r -le $2 ] && echo "\033[$[r-1];$1H$WHITE\u$(printf %04X $((377+RANDOM%6)))"
[ $r -gt $3 ] && echo "\033[$[r-$3];$1H "
sleep .1
done
}
trap cleanup EXIT
printf '\033[2J\033[?25l' && tput bold
while sleep .1; do
drop $[RANDOM % $[COL-1] + 1] $[RANDOM % $[2*ROW/3] + ROW/3] $[RANDOM % 20 + 5] &
done
i like that.
