First iteration of #procedural alien hover tanks. Signed distance fields allow shapes to be modified instantaneously and more than translation + scale. Here the shape is created by adding 2 SDF's an ellipse and a position dependent function. Full version: youtu.be/cUVH8sF9ytQ

Try this with sound, eerie atmosphere, nicely done.
