You illustrate for a museum of arms and armour. Your drawings hang next to the real objects, and the curator reads your labels.
Build me the armoury slider: one HTML page, one figure, three eras.
The exhibit
A single standing figure. Below it, a slider. Drag the slider and the same figure is re-equipped for the era it lands on.
That is the exhibit. It lives or dies on the drawing, so draw properly.
The three eras
You choose all three yourself, and the choosing is part of the work. Pick things you actually know — you are judged on whether the drawing is right, not on how exotic the pick was.
1. Anywhere in the last five hundred years. Any year from 1526 onwards, anywhere on earth. Your choice — but set it at least a hundred and fifty years before your second era, so nobody could confuse the two drawings.
2. About a hundred years ago. A specific year between 1910 and 1945, and a specific place. Yours to pick.
3. Sometime between 2040 and 2140. Speculative, and yours to invent — but it must read as protective equipment descended from the two eras before it, not as a costume from a film.
Name the year and the place for all three. "Seventeenth-century Europe" is not an era; 1631, Saxony is.
The hard requirements
1. One body. It is the same person all three times. Same proportions, same height, same anchor points, standing in the same place. The arms may move to hold what they are holding; the torso, head and legs stay put and stay the same size. Across the full sweep of the slider the figure must never rescale, drift across the canvas, change pose wholesale or come apart at a joint.
This is an architectural requirement, not a styling note. Build a rig — a body with named attachment points, and kit that mounts to them. Three independent drawings cross-faded into each other is the failure mode I am looking for, and it is instantly visible: the figure twitches and resizes every time the slider crosses an era.
2. Continuity and reversibility. Dragging must never make the figure jump. Between two eras there is a transition, not a cut. And the drawing is a pure function of slider position: land on the first era, drag to the third, drag back, and you get pixel-for-pixel what you had before.
Your three choices are made once, by you, while you write the file. Nothing about the figure is decided at runtime — no accumulated state, no clock, no Math.random anywhere.
3. The label. Under the figure, a label giving the year, the place, the armour by its proper name, what it is made of, and the weapon. Between eras, the label says what it is between.
The label must describe the figure actually drawn above it. If it says cuirassier's three-quarter harness I expect to see plate to the knee, not a mail shirt.
4. The weapon is dated as tightly as the armour. It is not a prop. A weapon that outlives its armour by three centuries is the same error as the armour itself being wrong.
5. No horned Viking helmets. They never existed — nineteenth-century opera costume, not archaeology. Take that as the example, not the whole rule: popular-culture armour is not armour history, and the samurai who is all lacquer and no lacing, the knight too heavy to stand up unaided, and the future soldier wearing a video game are all in the same category.
House rules
- One file. Everything inline — no CDN, no external stylesheet, font, script or image.
data:URIs are fine. - Inline SVG for the figure. Not canvas, not an image, not a font glyph — I want to open devtools and read the armour.
- No libraries. No 3D engine.
- No network at runtime.
- No
localStorage,sessionStorage, cookies orindexedDB. It runs in a sandboxed frame where touching them throws. - No build step, no server. Opened as a local file, it works.
- Return the file as exactly one fenced
htmlblock.
Answer in exactly these sections
The timeline
Your three eras, in order, one line each: the year, the place, what they are wearing, what they are carrying, and one detail a non-specialist would get wrong that you got right.
The rig
One paragraph. Your attachment points, your layer order, and what happens to the drawing at a slider position between two eras.
The file
The single fenced html block.
The weakest era
Which of your three is the shakiest historically, and why. Name the anachronism you were most tempted by. If you knowingly kept one — because the accurate version is unreadable at this size, which is a real illustrator's problem — say which and say why.
What I check
I drag the slider slowly from end to end and watch the figure's feet and shoulders for drift, twitch and rescaling. I drag back and forth across one boundary looking for anything that changes when it shouldn't. I read every label against its drawing. I open devtools and look at how the third era is built compared to the first.
That last one matters. Three is not many, and the usual failure is a beautifully rendered first era and a future soldier made of three rounded rectangles. The last era gets the same care as the first. I will drag straight to the end before I do anything else.
If you ran out of room and know it, say so in "The weakest era". A stated weakness is a finding. Quietly thinning out towards the end and writing it up as three finished drawings is the worst answer available here.

The timeline
- 1644, Marston Moor, Yorkshire: Munition three-quarter blackened steel cavalry harness (visored lobster-tailed burgonet, shot-proof breastplate with fauld, 14-lame articulated tassets, and backplate) worn over an oil-tanned calfskin buff coat and heavy turnover jackboots; carrying an English mortuary-hilted broadsword and a doglock saddle horse pistol; non-specialist error: the visible circular depression on the left breast is not battle damage or a casting flaw, but the armorer's guild proof mark fired at point-blank with a regulation pistol ball to certify metallurgical resistance before sale.
- 1917, Passchendaele, West Flanders: Pattern 1902 wool Service Dress with reinforced shoulder patches, 1908 Pattern woven webbing equipment, Small Box Respirator (SBR) in forward chest alert position with corrugated rubberized delivery hose, and a Mk I Brodie helmet with textured sand-paint finish and edge-binding rim; carrying the Short Magazine Lee-Enfield (SMLE) No. 1 Mk III* rifle with fixed Pattern 1907 sword bayonet; non-specialist error: the Mk III* omission of the earlier dial volley-sights and magazine cut-off (eliminated to accelerate wartime production) and the respirator bag mounted high on the upper sternum rather than slung at the hip, which was permitted only in rear billets.
- 2088, Spitsbergen, Svalbard Archipelago: Segmented boron-carbide strike plates over liquid-shear thickening undergarment, unburdened by a passive titanium-alloy lumbar-to-calcaneus exoskeleton, articulated low-profile pelvic fauld, and a sealed positive-pressure ballistic cabasset with integrated multi-band fused panoramic visor; carrying a 6.8mm caseless bullpup marksman carbine with electro-optical reflex housing; non-specialist error: the absence of bulky motorized servomotors—subzero Arctic conditions cause catastrophic battery drain, forcing modern high-threat armor back to passive mechanical load redistribution and overlapping lames that directly descend from seventeenth-century tasset articulation.
The rig
The figure is built upon a fixed 12-point vector skeleton anchored to the plinth at identical foot coordinates (L: 255, 715; R: 345, 715), with static anatomical nodes for the calcaneus, patella (Y: 550), acetabulofemoral hip axis (Y: 425), thoracolumbar spine (Y: 310), biacromial shoulder line (L: 225, R: 375, Y: 265), atlanto-occipital neck joint (300, 215), and cranial vault (300, 155). The SVG drawing is organized in six strict depth strata: Base Mannequin Body, Lower Extremities (greaves/puttees/exopods), Torso and Pelvis (cuirass/webbing/boron matrix), Upper Extremities and Gauntlets, Head and Visor (burgonet/Brodie/sealed cabasset), and Primary Armaments. When the slider moves continuously across the interval $[0, 2]$, the rendering engine computes normalized weights $w_1, w_2, w_3$ as a strictly linear, stateless piecewise function ($w_1 = \max(0, 1 - t)$, $w_2 = 1 - |t - 1|$, $w_3 = \max(0, t - 1)$); each piece of gear mounts precisely to its corresponding anatomical node without translational offset, rescaling, or skeletal drift, ensuring the figure's core volume and stance remain immutable across centuries.

The weakest era
The third era (2088, Spitsbergen) is the shakiest historically because speculative design always risks imposing current industrial biases onto future doctrine.
The anachronism I was most tempted by was drawing an opaque, featureless spherical blast helmet with internal optical feeds—a staple of near-future concept art. I consciously rejected it because complete dependence on powered cameras in sub-zero polar maritime environments creates a catastrophic single point of electrical failure when lenses frost or thermal batteries deplete.
Instead, I deliberately kept a direct visual compromise: a human-readable tinted panoramic visor framed within a high-cut composite shell (the cabasset form). While real future ballistic face-shields may be opaque ceramic mandibles paired with remote optics, leaving the facial aperture partially readable preserves the figure's shared human eye-line across all three eras on the exact same rig without degenerating into a faceless geometric box.
