Here's some comics at Pixton (yeah, they're mine)
that will give you an idea of the simplicity of using their app to make a comic - if I
can do it, anyone can! The sign-up is free, and, honestly, it takes just a short while to be really accomplished at making these.
- it's a great piece of software that allows you and your students to make comments on a slide show, as well as easily add text and voice to a presentation. My grad class is using it, and it definitely is worth the look - not that expensive, and easy to learn - very intuitive.
Meanwhile, my Kindle LOVE continues to grow. It's lightweight, easily updatable, and easy to read under a variety of lighting conditions. I just returned from vacation, and used it on the trip, and once I arrived.
