Harry Potter with the old William S. Twist
Watch this for 9 minutes. If you like it, go to Illegal Art's entry page for Wzard People, Dear Reader and download the audio, then go rent/torrent Harry Potter and watch the rest. I was sitting in a small, salty puddle of tears, tears of joy.
Harry Potter always need more Mugwamps.
Edit: This had a NYT article about it so, I'm sure its been bboinged, but i'm a huge hypocripple.

Truly fantastic.
Makes me remember to go buy tickets for the Black Rider show here.
