|---|---|---|---|---|
| A map of the world from memory Drawing · 10 models |
The most complete map. The outlines are as good as Opus's, and it adds Lake Victoria, Lake Baikal, the Caspian, a white Antarctica and twelve named seas, from the Bering Sea to the Tasman Sea. The ocean labels sit in open water and in the right places. The only flaws are in the labels: "Sea of Japan" runs onto Japan, and the large "NORTH AMERICA" and "SOUTH AMERICA" spill over their coasts. | 4 of 4 | 474 s | $1.927 |
| Draw a unicorn Drawing · 10 models |
Similar to Opus: an oval white body, four legs with purple hooves, a gradient mane and tail and a gold horn. The scalloped mane and tail are tidier, but the neck is again an angular block with a visible seam where it meets the body. | 2.5 of 3 | 41 s | $0.159 |
| The Starry Night, redrawn in SVG Drawing · 10 models |
A sky stitched from dashed strokes, with two loose spiral clusters, stars in dashed gold halos and a crescent moon in a large ringed halo. The cypress hugs the left edge with mottled green dabs and a forked tip, and the village is small houses scattered around a church with a cross. The distortion filter leaves thin unpainted white gaps at the left and right edges of the sky, and it was the most expensive answer. | 4 of 4 | 255 s | $0.978 |
| Ball bouncing in a spinning hexagon Simulation · 10 models |
Very close to Opus: a blue hexagon spinning at 1.2 rad/s, a striped ball with a trail and small sparks on impact, sliders, and click-to-drop or drag-to-throw. The bounces are lively and stay inside. The slider panel covers the left corner of the hexagon as it turns past, and this was the most expensive answer. | 3 of 3 | 84 s | $0.390 |
| The solar system, to scale in time Animation · 10 models |
A clean dark view with real periods and start positions from 1 January 2000, a date readout, slower, faster, reset buttons and a "true distances" switch. Speeds are right (Mercury 4.1 laps per Earth year). In a 1000 by 700 frame the control panel sits over Neptune at the start (it shows in a larger window), and it was the most expensive answer. | 3 of 3 | 93 s | $0.420 |
| A product page from one feed row Business · 10 models |
A tidy page with three socks laid side by side, a quantity stepper in packs and four fact cards (material, care, pack, weight). The copy keeps to the feed and adds one sensible line: all three pairs are the size you select. Adding gives an inline "Added 1 pack — size M (UK 6–8) — to your basket.", a toast and a basket count; the most expensive answer at $0.55. | 5 of 5 | 117 s | $0.550 |
| A pricing table with a monthly/yearly switch Web page · 10 models |
A toggle switch between "Monthly" and "Yearly", with a line underneath that tells you the other prices ("Showing yearly prices. Pay monthly and Team is £6 and Business is £11"). Prices and "Billed yearly" notes switch correctly both ways, Team is marked "Recommended", and the four FAQ answers repeat only the given facts. It was the most expensive answer. | 4 of 4 | 66 s | $0.328 |
| Pelican riding a bicycle Drawing · 10 models |
A simple flat drawing: an oval body, a straight neck, a round head with an orange pouch, on a black bicycle. The saddle is visible under the body, both feet reach the pedals and one wing stretches out to the handlebars. Plain but correct, and the most expensive of the short answers. | 3 of 3 | 25 s | $0.103 |
| Newton's cradle Simulation · 10 models |
A chrome frame drawn with a second, rear top bar for depth and V-shaped double strings; it starts with the end ball already swinging. Drag and transfer work cleanly, and the swing dies down over about eight seconds. The most expensive answer, at $0.97. | 3 of 3 | 222 s | $0.966 |
| A newsletter email that works in email Business · 10 models |
The most fully written answer: "Colour No. 07 — Moss", five washing rules and a subscriber offer box, with dark mode handled throughout except a "Shop the range" button that loses its fill. Almost every business detail is made up: "78% extra-fine merino", "hand-linked in Yorkshire", "Sizes UK 4–13", "One use per customer. Can't be combined with other offers", and an address at "Unit 4, Beck Mill, Hebden Bridge". It is also the dearest answer. | 4 of 5 | 120 s | $0.574 |
| A landing page for a photo-book app Web page · 10 models |
The best-written copy ("Your best photos are stuck on your phone. Let a few out."), with the offer in a pill above the headline and a clear "What £19 gets you" list. It adds a £15 second copy, a reprint-or-refund promise and three named testimonials. On a phone the page scrolls 68 px sideways: the hero book hangs off the left edge and the email "Send the link" button is cut off on the right. | 2 of 3 | 273 s | $1.180 |
| The jelly effect: ten frontier models, one prompt Animation · 10 models |
A pink jelly dome with a small face on a plate, and six colour swatches. A click dents it and it wobbles; dragging leans it over and pulls it taller, and it bounces back to its round shape within about two seconds. Well made but gentler than Opus's jelly, and at $1.36 the dearest answer on the page. | 3 of 3 | 320 s | $1.361 |
| Conway's Game of Life Simulation · 10 models |
A compact 80 by 50 board with a pattern dropdown, a "Place at center" button, a wrap toggle (on by default) and keyboard shortcuts listed under the toolbar. The blinker, glider, pulsar and gun all behave correctly, and the gun had fired two gliders after 85 generations. As correct as Opus, but at $0.51 it is the most expensive answer on the page. | 4 of 4 | 104 s | $0.508 |
| Flappy Bird in one file Game · 10 models |
Very close to Opus's game: the classic look, a "Flappy Bird" title screen and a Game Over panel with "NEW BEST!". We passed 10 pipes; clicking into the top pipe ended the run at once, and the restart goes back to a ready screen showing "Best: 10". Solid, but the most expensive answer here. | 4 of 4 | 81 s | $0.392 |
| Chess with every rule Game · 10 models |
A compact board with the status in a bar above it, which turns red for "Black to move - Check!" and green for "Checkmate! White wins." All four sequences played correctly, and it offers promotion with a choice of four pieces. It is correct, with undo and a flip button, but it was the most expensive answer by far. | 5 of 5 | 176 s | $0.859 |
| A category page from a product feed Business · 10 models |
"WetWeather.co": a tidy three-column grid with checkbox filters, colour counts and a price slider paired with number boxes. All the filters and sorts gave the right jackets. It does add "Bestseller" badges to the Ridgeback trail jackets, a sales claim the feed does not make. It was also the most expensive answer by far. | 3.5 of 4 | 172 s | $0.816 |
| An animated SVG logo Drawing · 10 models Our pick |
A dark navy card: an amber swept-wing bird flies in from the left with speed lines, the letters of "KESTREL" slide in one by one, then a gold rule and "SWIFT DELIVERY" settle beneath. Every element is aligned and the motion ends cleanly before 2 seconds. The most polished resting logo, but also the most expensive answer by far. | 4 of 4 | 199 s | $0.734 |
| An analogue clock that tells the time Drawing · 10 models |
A classic cream dial with black Roman numerals, a gold case and a red second hand with a counterweight, labelled "CHRONOS". The hands showed the correct time and the hour hand sat halfway between IIII and V at 4:28. Clean and correct, but the most expensive answer on the page. | 4 of 4 | 41 s | $0.188 |
