I've been bugging cartoonist extraordinaire Jason Shiga to put his recently released book Meanwhile, a tour de force "choose-your-own-adventure"-type comic book into a format that's more web-friendly.
Meanwhile starts with a simple choice: Vanilla or Chocolate ice cream? Either choice (which you, as a reader, make) will lead the protagonist Jimmy into an adventure involving a mind reader, a time machine, and even a "Killitron," a device that wipes all life on earth (aside from the user). Confused? Laughing Squid has the interview with Jason that explains it all (with a very cool photo of Jason in front of the panel of possibilities that will blow your mind).
The series of choices Jimmy ... er, you have to make in the book leads to 3,856 story possibilities - so this is definitely a book that you'll "read" more than just a few times. Some possibilities are so maddeningly hard to get to - and unless you cheat and peek - it'll mean hours upon hours of fun :)
I'm sure that Jason will work something very cool web version out for the book. Meanwhile (see what I did there?), check this out: Jason's YouTube tutorial on how to make your own interactive comic.
