Kapow! is a web-based application that allows you to read your graphic novel/comic book library (CBR and CBZ files) on your iPhone or iPod Touch. It has some neat features:

• Scales to page width in portrait and landscape mode.
• Double-tap to intelligently zoom in.
• Subsequent pages are preloaded - you rarely have to wait when turning the page.
• The book and page you're reading are stored, so you can easily find where you were up to.
• Browse your comics using your filesystem's hierarchy.
• Optionally resize images before sending, to reduce bandwidth use.

The Kapow! project is an open source endeavour, available under the MIT license included with this distribution. It was initiated by Joseph Pearson of Inventive Labs (http://www.inventivelabs.com.au), using the Sinatra web application framework and Prototype-flavoured Javascript.
