One fun activity we can work on in our makerspace allows us to personalize movie posters using nothing more than powerpoint. There is a pretty powerful photo editing component to powerpoint that few people take advantage of, or even know about. Granted it is not nearly as seemless as photoshop, but it gets the job done, and we have access without spending a dime.
View the slideshow below to get an idea of what we can accomplish. These movie posters were made for our 8th grade Automation and Robotics class.
