I love web-based applications. Especially the ones without software installs, feature-comprehensive, optional registration, local-saves, and no-frills free usage! This app can be found here: http://www.piskelapp.com/
Here's something that I just cooked up. The .piksel file that I made can be found here (you may load it up on your side): https://drive.google.com/file/d/0B9bA1lYIwx-KREZVYjF1UmlzSVk/view?usp=sharing
Have fun messing around with the neat little app!
