You have several ways to animate things while doing computation.
One technique is to keep your sequence, and create a local variable for
your Boolean that you want to animate. Put the local variable writes in
the frames where you want to change its state. I didn't completely
understand whether you wanted it to blink or what.
A different, and in my opinion, better approach would be to make a very
simple state machine. Popup on the sequence and replace it with a case
statement. Place a while loop around it and wire i to the ? terminal.
With no other changes, this will now execute your frames in sequence,
just like before, but you have the option to set the Boolean each
iteration of the loop, you can more easily have state info pass from
frame to frame, and any frame can abort the sequence by affecting the
loop's continuation terminal.
Still another approach, that affects your code less is to make a
completely parallel loop that does your animation at whatever rate you
want. It is really a state machine whose state is controlled by your
sequence frames. You change the state variable from hidden to first,
second, third, and so on. At the end of the sequence you set it back to
hidden.
