Slippery Shapes

How it works, and what it shows: read the note on the blog.

Steer the Flow Six bodies and a flow you can steer, traced through the real velocity field.
Stretch a Vortex Stretch a vortex toward a blowup and see what the real fluid does first.
Strange Water Waves that catch each other up into one rogue wave. A ship's wake that keeps the same angle at any speed, until the boat goes fast. Two waves that pass straight through each other. Water that jumps up and stands still.

Every simulator runs on our own engine and shows its working. The notes on the blog explain how they work.
