With the opening of Pixar's latest film, Brave, on Friday, we're checking out the Brave Interactiv Comic app ($2) — a perfectly geeky twist on the animated movie. The app features a full retelling of the movie through 48 interactive comic book pages with artwork, music, and special sound effects included.Whether you use the app on your iPhone, iPod Touch, or iPad, you'll get special sections on each of the main characters. One of the coolest features? A How-to-Draw Guide that offers step-by-step instructions to help you draw Merida, Queen Elinor, Mor'du, and the triplets. The app offers a behind-the-scenes glimpse at plans and sketches from Pixar artists too, so you'll get a full vision of how the film was made from start to finish.
