You are a size coder. You came up through 4k intros and JS1k, and you believe that a budget is not a limitation but the entire craft — anyone can be impressive with a megabyte.
I want something worth watching, and I am giving you 2048 bytes to do it in.
The budget
The finished HTML file must be 2048 bytes or fewer, counted as UTF-8, including the doctype, every tag, every space and every newline. That is the whole file. There is no second file.
House rules
- One file. Nothing external — no CDN, no stylesheet, no font, no script, no image.
data:URIs are allowed but they count against you like everything else. - No network at runtime. This is opened offline.
- No
localStorage,sessionStorage, cookies orindexedDB. It runs in a sandboxed frame where touching them throws. - No build step. Saved to disk and double-clicked, it runs.
- It must animate, and it must keep going — no three-second loop that then sits there.
What I don't want
I have seen these a thousand times and I will not be impressed:
- a starfield
- a rotating wireframe cube
- Matrix rain
- a bouncing ball
- a plasma or a rainbow sine wave
- a particle system that is only particles
- a lighthouse — and I mean the whole scene, not the word: the sweeping beam, the rocks, the night storm, the rain, the distant little boat. Swapping the tower for a radar dish, a searchlight or a lightship is the same answer wearing a hat.
Show me something with a subject. Something that is recognisably of something — a place, a weather, a creature, a machine, a mood — and not just maths made visible.
Answer in exactly these sections
The pitch
One line. What am I about to see when I open this file?
The file
Exactly one fenced html block, containing the whole file and nothing else.
The ledger
- Bytes: the exact byte count of the file above.
- How you counted: in one line.
- Last thing cut: the feature or detail you removed to fit, and what it would have added.
The technique
One short paragraph on the trick that bought you the most room. Not a list of micro-optimisations — the one structural decision that made the rest affordable.
On the count
I will run the file through a byte counter, so the number in your ledger is checkable and I am going to check it.
If you cannot get under 2048, hand me the smallest honest version you have and put the real number in the ledger. A 2600-byte file labelled 2600 scores well above a 2600-byte file labelled 1990. Going over is a miss. Lying about going over is the only thing here that is disqualifying.

The pitch
Three bioluminescent jellyfish pulse and drift through a dark column of deep sea, trailing tentacles and breathing cyan light while marine snow sinks past them.

The ledger
- Bytes: 1919
- How you counted: every character is ASCII so UTF-8 bytes = characters; 36 lines joined by 35
\n, no trailing newline (1884 + 35). - Last thing cut: gradient-stroked tentacle tips that fade to nothing — the tentacles currently end at a hard point instead of dissolving into the dark; it would have cost ~90 bytes I didn't have.
The technique
The whole scene hangs off one parametric function, J(cx,cy,scale,phase,alpha), where a single sine (p=sin(ph)) drives everything at once: the bell's width/height (narrow-and-tall on the power stroke, wide-and-flat on the relax), the scallop depth, the glow intensity, and — phase-shifted — the wave travelling down every tentacle. Because the pulse, the drift, and the appendage motion are all just readings of that one number, a jellyfish costs one function, and a bloom of three at different depths, scales and pulse-rates costs only three cheap calls. That's what left room for the oral arms, the inner core-glow, and the depth gradient behind them.
