interactive Frankenstein book app, you may like to try it out. And now you don't even need an iPad or iPhone, as development wizards Inkle have put a Frankenstein web demo up on their site. Pop over and have a conversation with Victor about what he's got in that tank - just click where you see the words "Give it a try."
This demo is the sort of thing that publishers ought to be putting up on their websites too, incidentally, not just leaving to developers. But we're only in 2012. Softly, softly.
Meanwhile, if you are iOS-enabled then you can buy the book here.
