How can I get through the clock pendulums?

Hint 1 of 13:

Good coordination with the hand and eye is definitely required.

Hint 2 of 13:

The spikes on the pendulums will kill you!

Hint 3 of 13:

I used the SHIFT and ARROW keys to run instead of my mouse.

Hint 4 of 13:

Your objective is to find a metal round wafer that is hidden inside the
clock.

Hint 5 of 13:

Pulling the lever on the outer wall starts the mechanism moving.

Hint 6 of 13:

Go up close to the first pendulum and watch it move from side to side.

Hint 7 of 13:

Run straight through the first one to the block beyond it.

Hint 8 of 13:

Pulling the lever here stops the first pendulum and starts the second.

Hint 9 of 13:

Now you should do a zigzag pattern through the side hallways, avoiding the
swinging pendulums.

Hint 10 of 13:

This time do not go straight through.  Instead, run to the right when it is
safe to do so.

Hint 11 of 13:

Find a lever in an indented alcove and pull it.  This will open a passage to
the North, stop the second pendulum, and start the third pendulum swinging.

Hint 12 of 13:

Keep darting in and out of the passageways until you have been through them
all.

Hint 13 of 13:

Somewhere down one of the side hallways is the "master key" for the door with
the mouth.
