a falling-sand atelier
Pick an element on the left, drag on the canvas to paint it. Right-click or hold Shift to erase. The Line tool drags out a straight line and paints it when you let go. The four spigots above the canvas start off: click a spigot's bars to start it pouring, its name to choose what it pours, and off to stop it.
Things to try: pour oil on water, then touch it with fire. Drop a seed on soil you have watered. Put a clone block in a stream. Light a fuse that runs to C-4.
Open the element guide: every element, and what it does to the others.
