I wanted to share this interactive animated project "A Short Trip

. With your right and left arrow keys, you can control the trolley's journey as it picks up passengers through a hand-illustrated countryside. The ambient sounds as the trolley moves through the landscape are really excellent. I loved interacting with this experience! My only critiques might be that it lacks adequate usability cues (or hints) about areas of action and that it doesn't provide an option to return to the beginning without reloading the page. Or at least I didn't see one.
If you visit this very cool project, come back to the IxD forum and share your thoughts with us.
