Helping out someone on the Processing forum. This slideshow is dynamic in two ways. First, because it sends polaroids randomly all over the place! Second, because it keeps checking the data directory for new images to include while the program is running. Extremely useful if coupled with a second program filling the directory with images, for example webcam snapshots.
Features include easing towards the target location, an autoplay function and the ability to add/remove slides manually. Take a look at the video to see it in action! Watch the HD-version here.
