This is for the SDS "Blending In". Move the mouse around the screen, and you will find that some numbers are hiding in the noise! To build your own object, click the pen icon, pick a layer to edit with the arrows, edit that layer with the pen, and click the top of any cube to fill or erase it. The X button leaves the layer you are editing. You can use the arrows to choose another, or use the checkmark to watch your creation Blend In!
