White blood cell

What you're seeing

1. Pale, deeply folded spheres drift among many red, disc-shaped cells against a blurred dark maroon background, with tiny white specks floating between them.
2. One folded sphere comes towards the camera and grows until it fills the upper right of the frame.
3. It then crosses to the left and ends partly out of frame at the left edge, while more red discs and smaller pale spheres tumble past.
