Today is the last day you can donate to the Kickstarter campaign for a choose-your-own-adventure style version of Shakespeare's classic play Hamlet. Launched by Ryan North, who is probably best known for creating Dinosaur Comics, the 80,000 word novel proposal has already raised more than $500,000, more than 25 times its original goal. The book, which will feature art from Kate Beaton, Andrew Hussie, Randall Munroe and Matthew Inman, has become the most-funded publishing Kickstarter of all time.
