A great example of the time-frequency (or space-frequency in this case) duality of fourier transforms. The math of the FT doesn't care about the "direction" that your going for the transform, so function that look similar in time/frequency will have similar FT in the frequency/time space.

In this case, embedding the frequency plot of the cat in the space plot of the women means that the FT of the women will cause the cat to appear, and vis-versa.
