I like this explanation. It would be good to include a little bit about why we even care to do frequency-domain analysis, and what a "transform" is.

this is a wonderful explanation and illustrates the importance of fourier transforms in a simple way anyone can grasp.

coupled with voidhorse's comment, it appears like "transform" obscures the concept whereas "translation" would be more appropriate and clearer.
