How about another variation:-
while true
   tput clear
   until [ $row -ge 23 ]
      until [ $col -ge 80 ]
         for char in "\\" "|" "/" "-" "*"
            tput cup $row $col
            echo "$char"
            tput cup 24 0
            sleep 1

This leave the cursor on the bottom line (of a 24x80 screen) after each character so that any messages could be displayed and not immediately overwritten.
