Wannamingo is an image processing application developed in JavaScript; you can use to adjust your images with various filters, image effects, cropping, blurring, sharpen and many many more. You can select images to import (from your phone gallery or computer) or import directly from the webcam.

The application started as an experiment in playing with HTML5 Canvas and it evolved from there.
