MOTOR
Cells · A kinesin molecular motor walks hand-over-hand along a microtubule, hauling a vesicle cargo — a whole city of machines inside the cell.

DNA
Cells · DNA replication — the full replisome in real-time 3D. Trombone loop, Okazaki fragments, click any enzyme to learn what it does.

MOLECULAR SOUP
Molecules · Particle Life — hundreds of dots, one rule: who attracts whom. Cells, membranes and predators self-organize. Tune the matrix, share your world.

WIREWORLD
Logic · Wireworld — a Turing-complete cellular automaton. Draw copper wires, fire electrons and assemble working logic: an electron gun, OR and XOR gates. Build a computer out of cells.

LIFE
Life · Evolution of artificial life — creatures hunt, flock and evolve through a maze. Free forever.

LENIA
Life · Continuous Conway's Life — math gives birth to smooth living creatures that swim, heal and collide. A zoo of real Lenia gliders: Orbium, Scutium and more.

ATP SYNTHASE
Cells · The most beautiful nanomachine in you — a rotary turbine. Protons pour through the membrane, spin the rotor, and the head stamps out ATP. ~10¹⁷ of them spinning in you right now.

ION CHANNEL
Cells · Your every thought — a running wave of charge. Click the membrane: voltage-gated channels flip Na⁺ in, the spike races down, K⁺ resets it behind. You're reading this as that wave.

MITOSIS
Cells · You began as one cell. The spindle grabs each chromosome by its centromere and rips the copies to opposite poles, then the cell splits in two. This dance repeated trillions of times — into you.

VESICLE TRANSPORT
Cells · Cargo delivery — a kinesin motor walks hand-over-hand along a microtubule hauling a vesicle, burning ATP each step, until SNAREs fuse it to the membrane and spill the cargo out.

TRANSLATION
Cells · Central dogma, final step — the ribosome reads the mRNA order three letters at a time, tRNAs deliver amino acids, and a protein chain is stitched and folds. The 3D-printer of you.

TRANSCRIPTION
Cells · Central dogma, step 1 — RNA polymerase rides your DNA, unzips it, and writes an mRNA copy that floats off to the protein factory. Your genes never act alone.

PROTEIN FOLDING
Cells · A floppy amino-acid chain collapses into a working 3D shape — hydrophobic core in, charges and H-bonds locking it. Heat it, watch it unfold and refold. Shape is function.

GENOME PACKING
Cells · Two metres of DNA into a nucleus smaller than dust. The helix winds onto histones → nucleosomes (beads on a string) → 30-nm fibre → loops → a chromosome. Pull the field, pack it tighter.

VIRAL INFECTION
Cells · A virus is just code. It docks to a receptor (key-and-lock), hijacks your ribosomes, forces them to build copies of itself — until the cell bursts and the new virions spill out to do it again.

IMMUNE RESPONSE
Cells · A virus is code; immunity is code that learned to read it. Y-shaped antibodies lock onto a matching epitope, B-cells mass-produce them, macrophages eat the tagged invaders — and memory cells make round two faster.

STAR
Game · A tiny star system waiting for an owner. Build extractors, pump ore, energy and crystal, ride out solar flares. It lives on its own — open, tweak, close.

ATOMS
Atoms · Pour charges — matter self-assembles by valence into H₂, H₂O, CH₄, digitizes into code and winds into a growing DNA helix. The beginning of the Universe.

SANDSPIEL
Molecules · Falling-sand alchemy — 16 elements with real rules. Pour lava, light forests, melt ice, watch acid eat through stone. Six instant scenes.

Scientific and product animations from Finekot. You bring the task — I own the taste, the accuracy and the QA. AI does the building; the brand guarantees the level. If it's from Finekot, it's a standard, not a gamble.

You · brief + idea→ Finekot · prompt · taste · QA→ You get · a clean animation
