var chosenColor: Paint;
chosenColor = black:Color;

var x = 120;
var y = 70;

    content: Group{
        transform: bind translate(x,y)
        content: [Star{
            points: sizeof colors
            rin: 30
            rout: 50
            fill: bind chosenColor
            onMouseDragged: operation(e) {
                x += e.localDragTranslation.x;
                y += e.localDragTranslation.y;
        foreach (i in [1..sizeof colors]) Circle {
            var: self
            transform: [rotate(i*360/sizeof colors,0,0), translate(50,0)]
            radius: 10
            fill: colors[i%sizeof colors]
            onMouseClicked: operation (e){
