no, that would work, and in that case you would be creating an html5/canvas document and using createjs/javascript.
to rotate your circles you would need a loop (eg, "ticker" or setInterval) where you update each circles rotation and you indicated you want the user to input different rotation speeds (with buttons). it might be better to use an input component to allow the user to input rotation speeds. eg, if ti is a textinput component (for the user to input rotation speed), and c1 and c2 were two of the circles:
this.ti.addEventListener("attached",ti_readyF.bind(this));
createjs.Ticker.addEventListener("tick", tickF.bind(this));
function tickF(){
if(!isNaN(this.r)){
this.c1.rotation += this.r;
this.c2.rotation += this.r*2;
}
}
function ti_readyF(){
$("#ti")[0].addEventListener("change",ti_changeF.bind(this));
}
function ti_changeF(e){
if(isNaN(Number(e.target.value))){
this.r = 0;
} else {
this.r = Number(e.target.value);
}
}
