|---|---|---|---|---|
| A map of the world from memory Drawing · 10 models |
A plain, very simplified map. Africa, South America and Australia are recognisable, and Madagascar, Japan and New Zealand are there, but Europe is a block with no Scandinavia and Central America is a rectangle. It has no continent names, and the "SOUTH ATLANTIC OCEAN" label is printed across South America. | 3 of 4 | 115 s | $0.055 |
| Draw a unicorn Drawing · 10 models |
A bold-outlined cartoon with a round head, ball-shaped mane, crescent tail and a striped horn. The neck is a separate rounded bar hanging in front of the body like an arm, and two large white ellipses sit on the ground on either side for no clear reason. | 1.5 of 3 | 69 s | $0.027 |
| The Starry Night, redrawn in SVG Drawing · 10 models |
Has the right parts in roughly the right places, but painted in thick smooth stripes rather than strokes: the stars are flat yellow ovals (some with spikes, like lamps), the moon a pale disc in a haze and the swirl a single dark curl. The village is a few flat beige boxes around a stubby church tower, and a translucent grey band cuts across the foot of the cypress. | 2.5 of 4 | 231 s | $0.038 |
| Ball bouncing in a spinning hexagon Simulation · 10 models |
A thick, glowing cyan hexagon turning at 0.6 rad/s, with a pink ball, a trail and a slider panel. Bounces are correct and fade to rolling along the bottom walls. The panel sits over the left part of the hexagon, so the ball is sometimes hidden behind it. | 3 of 3 | 90 s | $0.027 |
| The solar system, to scale in time Animation · 10 models |
A busy page with a yellow header bar, slower, pause, faster, reset buttons, a speed slider and a strip of real periods along the bottom. Speeds are correct (Mercury about 4.2 laps per Earth year in our tracking) and each button halves or doubles them. A stray line in the footer, "drag? no — top-down view", looks like a note the model left for itself. | 3 of 3 | 159 s | $0.029 |
| A product page from one feed row Business · 10 models |
Blocky, boot-like socks overlapping on a beige card, a details table and a "Pack contents" row ("charcoal ×1, oat ×1, moss ×1"). The copy is the feed restated with nothing added. Adding with no size gives "Please select a size: S, M or L.", and with a size a toast and basket count. | 5 of 5 | 82 s | $0.033 |
| A pricing table with a monthly/yearly switch Web page · 10 models |
A compact light page with an iOS-style switch, a "Most popular" Team card tinted lilac, and a three-item FAQ in native disclosure rows. The switch moves the prices to £5 and £9 "billed yearly" and back, and nothing is added beyond the brief. Correct and simple, for under 2 cents. | 4 of 4 | 44 s | $0.019 |
| Pelican riding a bicycle Drawing · 10 models |
A cartoon pelican with headphones, a red scarf and pink cheeks on a red bicycle by a road. Both feet are on the pedals and a stiff wing reaches forward to the stem, covering the handlebars. Odd white spikes stick out of the back of the head. | 3 of 3 | 55 s | $0.021 |
| Newton's cradle Simulation · 10 models |
A plain grey cradle in a card, with a reset button and a "click" sound option. It behaves correctly: the far ball swings out, the middle balls stay still, and the swing fades slowly, still visible at 20 seconds and at rest by 40. | 3 of 3 | 197 s | $0.061 |
| A newsletter email that works in email Business · 10 models |
The busiest layout, with a dark hero holding an SVG pair of socks, a "Pairs well with" swatch row and three tip cards; in dark mode AUTUMN15 turns dark green on near-black and can barely be read. It invents a price and a shipping policy ("£16 a pair", "Free UK shipping over £30"). It also adds stock levels ("Charcoal: Low stock"), terms ("One per customer, can't be combined") and a Sheffield address. | 3.5 of 5 | 61 s | $0.028 |
| A landing page for a photo-book app Web page · 10 models |
A friendly page with a theme picker and a copies counter, but the offer keeps changing. A "Free UK delivery" launch banner sits above a price already sold as "£19 all-in". The page also adds 2 for £36, 3 for £51, a £4 four-day rush, £3 off for joining the waitlist and invented numbers (3,200+ reviews, 12,000 books, 1,240 trees). The "Get the app" button in the desktop menu is dark text on dark green and can't be read. | 2 of 3 | 109 s | $0.045 |
| The jelly effect: ten frontier models, one prompt Animation · 10 models |
A tall glossy dome with a face on a plate ("squishy jelly"), flavour buttons and a wobble meter. A click makes it wink and bulges one side slightly; dragging pushes out a lopsided lump, with a small jagged tip, while the rest of the body barely moves. It is back in shape within a second, so it reads as stiff rather than wobbly. | 2 of 3 | 157 s | $0.049 |
| Conway's Game of Life Simulation · 10 models |
A tidy board of exactly 60 by 40 with cyan cells, a dead border and buttons that drop each pattern in the centre. The rules are right (the blinker flips, the glider glides, the pulsar repeats every three steps), but the Gosper gun is drawn wrongly: its left half is a ring, not the real pattern, and after 90 generations it has churned into debris without firing a single glider. | 3.5 of 4 | 99 s | $0.035 |
| Flappy Bird in one file Game · 10 models |
A bright version with an orange bird, puffy clouds and a cream Game Over card with a "NEW BEST!" ribbon and an orange Restart button. We passed 11 pipes; the screen flashes white on the crash, and restarting begins again at 0. One of the cleanest all-round games. | 4 of 4 | 202 s | $0.033 |
| Chess with every rule Game · 10 models |
A clean board under a "White to move" bar, with the moves written in one line beneath it. Every sequence worked; checkmate and stalemate each dim the board behind a "Game Over" box, and promotion opens a piece picker. A correct, plain answer and one of the cheapest. | 5 of 5 | 233 s | $0.052 |
| A category page from a product feed Business · 10 models |
A plain shop with counted checkboxes, including four price bands that each return the right jackets, and each product's feed ID printed under its card. Every filter and sort was correct. It adds "Free delivery over £75 • 60-day returns" to the header, and the jackets look more like short-sleeved shirts. | 3 of 4 | 197 s | $0.045 |
| An animated SVG logo Drawing · 10 models |
Speed lines draw in, an abstract orange-and-white chevron mark flies into place, then a wide white "KESTREL" fades up with an orange bar and "SWIFT DELIVERY". Clean, centred and readable, though the mark is just stacked shapes and does not suggest a bird. | 4 of 4 | 45 s | $0.016 |
| An analogue clock that tells the time Drawing · 10 models |
A navy and gold "AURUM" dial with bold white numerals, a pink second hand, a date pill and a digital readout with the time zone. The time was correct and the hour hand moves in proportion. The date pill sits under the hands near the centre, so the hands cross it. | 4 of 4 | 76 s | $0.025 |
