Cool !

Firefox raises an exception:

    this.canvas = document.createElement('canvas');

    /** .... */
    this.captureStream = this.canvas.captureStream(0);

The problem is that the context isn't created before captureStream.


Have you considered using WebGL and shaders for filters instead? We
may benefit from acceleration and we could add trippy shaders too!
