I gave iamsittinginaroom.py a real spin yesterday on my stereo speakers (though still with just the built-in laptop mic). It doesn't waste any time in going to that weird feedbackish sound. Like third iteration (and I'm running it at five second intervals for testing). The only downside is there's a gap between iterations (there's a delay before playback and it takes longer to play than record for some reason so I'm not sure if once I make the interval longer it'll be that big of a deal or if it'll be worth the effort anyway, we shall see). Not too much else otherwise, normal day at work and all.
