Purely for the record: You could mention at least once, that there is some time something like Chirplet transform (http://en.wikipedia.org/wiki/Chirplet_transform). Never mind. Maybe next time. Even so, quite interesting reading.

Re: Chirplet transform
How you tell the story depends a bit on the direction you're coming from. Chirplets are a special case of (and recoining of the terminology from) Gabor atoms as seen through the lens of wavelet math.
Anyway, mentioning chirplets would be something of a red herring in the narrative. We're not using that formulation, and our purpose is closer to Gabor's. Chirplets are certainly related, but if we're travelling from point A to point B, they're point C on a parallel highway. The demo pages are already getting wicked huge, I must resist them becoming generalized DSP primers :-)
tl;dr: You have a point. But I didn't go into them for reasons of keeping on topic.
