This is a demonstration of the new VocabSushi iPhone / iPod Touch / iPad app by Jeff Novich.
He did this demo during an EDUKWEST interview and it gives you a great overview on the functionalities of this stand alone product. You don’t need to be a subscriber to the main VocabSushi offer to use the application.
The VocabSushi app comes with two free books, the classics “Oliver Twist” and “Twenty Thousand Leagues under the Sea”. You can then purchase more classic books inside the app for one or two USD, depending on the difficulty level and the number of vocab in the book.
Update: Jeff shared another video where you can see the screen more clearly:
