Writer Mark Waid has a free proof-of-concept zombie comic you can download. I opened it on my iPad and loaded it in iBooks, which gave me a one page at at time view rather than scrolling down in Safari.
Waid will soon be launching a new digital comics initiative. He’s spent a lot of time thinking about stuff like how big each page for be and how many panels a digital comic should have. He’s not trying to reinvent the wheel with lame animations, just designing comics for the screen first.
