pendulum animation

In today studio session I animated a pendulum using special see through paper. This was a first and a very nice experience really enjoyed drawing the entire animation by hand. Similar technique to the flip books however can created a much neater animation. I then scanned in each frame and put the animation together on photoshop. For my next animation task (to create a short pose to pose animation I would like to use a similar technique but with something more complex as I it will be an interesting challenge.
