Today Random House released an iPad app that allows you to explore the entirety of Ankh Morpork in both an isometric and top down views, with searchable locations, sound effects, information on all the hot spots and even strolling people. Check out the video (from the Guardian) and their review: Discworld: The Ankh-Morpork Map for iPad - review | Books | guardian.co.uk

I'm downloading it now - it looks fantastic. I've spent a lot of time in Ankh Morpork with my head in a book. I'm so excited to see this arrive on the iPad. Also, this is an amazing example of an interactive iPad map. I'm looking at this and looking at my own city maps and thinking hmmmmm.

The app is £9.99 on the UK store, or $13.99 on the US store.
