Auscultation tutorials

We're coming up on auscultation quizzes in Physical/Clinical Diagnosis, so I've been sorting through tutorials online. I need lots of repetition for tasks that involve memory-based auditory discrimination, so the more the better.

• Blaufuss -- some very nice tutorials with clinical scenarios, visual depictions and testing. I looked at "Heart Sounds Quiz" in particular.
  
• Cardiology site has a very extensive site of heart sounds, including many pathological.
  
• a basic set of lung sounds from RALES
  
• basic set of heart and lung sounds from 3M
  
• nice set of lung sounds from UC Davis, the one from which I made an iFlash deck of flashcards
  
• and lastly, if you own Bates Guide to Physical Examination, there are updated versions of HeartSounds available, most importantly one that runs kindof-natively in OS X. (I was really impressed that I was able to get the author's email from the readme on the CD, email him, and get a response with the updated app info directly from him within a day. Thanks, Dr Pitts!)
  

All in all, the winner is Blaufuss: Heart Sounds Tutorial.

Oh, and an amazing database of ophthalmology images.
