A 3D configurator for light art, with AR on your own wall

I moved the shop from Webflow to Astro and built a 3D configurator with AR. All 570 old URLs from Google Search still work.

One click swaps the artwork in the configurator's 3D scene, and the heading, size and price update instantly.

The starting point

What was missing before

In her studio in Busdorf near Schleswig, Kathrin Geller makes light art for the wall, every piece by hand and to order. Her buyers are private customers, hotels, practices and offices. One of her Google reviews explains why buying online is hard: “No photo can show it the way it really looks.” (translated from German)

A piece only comes alive with light, in a room and at the right size. Then there is the pricing logic: the size is width plus height in centimeters, and Galaxy alone comes in 34 sizes. And 76% of clicks from Google Search came from phones, where there is little screen space to show light, room and size.

Until August 2026, the shop ran on Webflow, extended with my own code since spring 2025. Even so, the audit before the migration found gaps: anyone who typed ateliergeller.de without www got an error page, although that address had brought in 127 clicks from Google. People found the studio almost only by its name: among the 1,000 most frequent search terms, terms with the studio's name brought 9,806 clicks, and all other terms combined brought 129. On August 26, 2026, the old site only showed a 404 page, so I brought the migration forward.

Approach

How I approached it

01

Two ways to buy on every artwork page

The “As shown” tab sells exactly the piece in the photo at a fixed price, paid by invoice. The second tab, “Design your own”, starts with the same version and lets you change size, light, color and texture, while a dimension sketch shows the size on the wall. Only once you change something does the page visibly switch to “Made for you”, with the matching note on the right of withdrawal.

On the Galaxy artwork page, one click switches from the photographed piece to the “Design your own” tab.

02

Artwork, light and room in 3D

At konfigurator.ateliergeller.de, 16 artworks are available in 3D, in five rooms from a living room to a sideboard. I generated the textures from Kathrin's sample photos. Artwork, light color and brightness change the scene instantly, the price updates with them, and every selection is stored in the URL, so it can be sent as a link.

In the configurator, the light switches from warm white to Philips Hue, the moon and the light rim glow blue, and the surcharge appears in the bar.

03

On phones, the artwork stays in view

On a phone, the controls take up three screens. So the 3D view stays fixed at the top, and size, price and inquiry sit in a fixed bar at the bottom. Change the size and you see the artwork grow in the room and the new price at the same time.

On a phone, a tap on plus enlarges the artwork in the room, and the fixed bar at the bottom shows the new price.

04

The artwork on your own wall

On a phone, the “On your wall” button uses AR to place the chosen artwork on the wall at actual size; on desktop, a QR code carries the selection over to the phone. For iPhone, the site builds the AR file itself. If you prefer a photo, you can place the artwork true to scale on a picture of your own wall, and the photo never leaves the device.

On desktop, “On your wall” opens a QR code that brings the chosen version to the phone.

Result

What it achieved

No known URL was lost in the migration. I fetched all 570 old URLs from the Search Console exports, and every one ends in status 200. Behind this are 193 redirect rules, and a test script checks them before every publish. The address without www responds again, too. On mobile, Lighthouse gives the homepage 100 each for accessibility, SEO and best practices, and 69 for performance (October 9, 2026).

For search, there is only one full month so far. In September 2026, Google sent 973 clicks, 5.6% fewer than in September 2025, with 15.6% more impressions. That does not prove growth. In January, I'll compare October to December with the previous year, Christmas season included. I haven't analyzed orders, inquiries or configurator use yet; the configurator is online but not yet linked from the website.
