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
A solitary Japanese Torii gate stands in a mountain lake at dusk as cherry blossoms drift in the wind and koi fish swim through the rippled reflections below.

The ledger
- Bytes: 1898
- How you counted: Measured the exact UTF-8 byte length of the raw block content (including the 30 newlines) with
Blob([str]).size/wc -c. - Last thing cut: Rippling concentric water rings around the base of the Torii pillars and wherever a cherry blossom hits the lake surface. It would have physically tied the falling petals and the architecture into the water plane instead of having the blossoms simply fade out as they cross the horizon.
The technique
Instead of duplicating geometry or maintaining mirrored coordinate systems for the water reflection, the script renders only the top 62% of the canvas (the sky, sun, mountains, Torii gate, and swaying lantern), and then uses the canvas as its own texture source via C.drawImage(c, 0, sy, W, 2, o, y, W, 2) in a 2-pixel scanline loop down to the bottom of the screen. By feeding sine-wave horizontal offsets (o) and a slightly compressed vertical sample coordinate (sy) into that self-blit loop, followed by a depth-attenuated dark purple fillRect pass, the entire animated reflection, water perspective, and surface ripple mechanics are achieved in 180 bytes of code.
