Has anyone made a nice real-time spectrogram[1] patch? The spectrogram.pd patch that comes with gridflow is pretty close to what I'm looking for, except that it doesn't display any past data, but I figured before i started figuring out how gridflow works I'd check to see if anyone had done the work before. (Or a gem-based one).

I was just adding a cepstrogram patch to the examples package for my timbreID externs. I modified it and made a spectrogram example too. It's not real time though - you just load samples and it plots spectrograms using Pd's struct & scalar objects. If you want to take a look at it, you can download the externs and examples at my site: www.williambrent.com.
Here's a screenshot of a horrific soprano vibrato sample.
Great! I'm checking out your TimbreID externs now.
A while ago I was working on a set of externs to train and use hidden markov models, so a robust set of feature extractors in PD would be a great addition!
we'll see if I pick up the project again...
