+# distort_faces
+This is a javascript and html5 implementation of one of my old flash pseudo fish-eye distortion effect. 
+
+I know it's very juvenile, but boy do I get a kick and laughters out of distorting faces of my family members, friends, and colleagues :D . I hope you enjoy it too :D
+
+
+## Features
+* tunables to allow control over the effects (radius, scale, scale easing)
+* 100% client-side code, including "upload" and "download"
+* primitive multi-blob support (keyboard-controlled, works as long as the blob do not overlap)
+
+
+## Demo
+
+Play with [the demo](timotheegroleau.com/fun/distort_faces/) with 3 sample pics of my kids and I to get you started.
+
+
+## How it works?
+
+The algorithm is not based on some fancy pixel manipulation, but on a naive "intuitive" implementation instead.
+
+The effect works by drawing concentric circles with diminishing radii on top of each other. In each circle, the pic is drawn again at a different scale. All the pics are drawn centered on the same point, relative to their scale.
+The circles are decreasing by one pixels at each layer, but the scale the image is drawn at is controlled by an easing function.
+The easing funcion that give the best results are typically ```linear```, ```swing```, ```easeInSine```.
