Ah, of course – sorry, didn’t try it out, but you’re right, those new elements are now of course shuffled separately. I think the solution is to actually create the shapes directly in PCIbex, rather than using a white.png and black.png image; and then just superimpose them on a pre-generated grid. This way, you can easily hide and make visible the same image (or else update its color properties). e.g.
newCanvas(“black”, 50, 50).color(“black”).css(“border-radius”,”100%”)
Will give you a black dot, which you can update to white or hide it to make it disappear etc.
