226 KBA jar of honey you can stir. Viscous fluid with a dipper you drag through it, refraction through the glass, HDRI lighting and a real depth-of-field pass with a focus control. Built on Three.js r170.
Heaviest of the three — it fetches Three.js and its HDRI maps over the network and compiles shaders on start, so it needs a connection and a moment before the jar appears.
