Fourier Series Animation: Examples to Inspire Students

[matqkks]

Are there any resources which show Fourier series approximating a given waveform? I am looking for examples which have a real impact on students and provides motivation. I am trying to find something visual but it could be just audio based. Something to start the topic of Fourier series so that students are inspired to study this difficult topic.
