A 3D configurator for light art, with AR on your own wall
3D and AR
Buyers design their piece in 3D and see it at full size on their own wall via AR.
Easy updates
Kathrin sends new pieces via WhatsApp, and import scripts add them to the shop.
Tracking
Every step from viewing a piece to placing an order reaches web analytics and the ad account after consent.
Starting point
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, and many pieces come in dozens of sizes. Most visitors arrive on a phone, where there is little room to show light, space and size.
Until August 2026, the shop ran on Webflow, extended with my own code since spring 2025. When the old site only showed error pages at the end of August, I brought the move to a custom shop forward, without losing a single URL from Google Search.
Approach
- 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.
- 02
Artwork, light and room in 3D
In the configurator, the pieces stand in 3D in different rooms, from a living room to a sideboard. Artwork, light color and brightness change the scene instantly, the price updates with them, and every selection can be shared as a link.
- 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.
- 04
The artwork on your own wall
On a phone, a button uses AR to place the chosen piece on your own wall at actual size; on desktop, a QR code carries the selection over to the phone. If you prefer a photo, you can place the piece true to scale on a picture of your own wall, and the photo never leaves the device.
Result
No URL was lost in the move: all 570 old URLs from Google Search lead to the right page, and a test script checks the redirects before every publish. The address without www works again, too.
Buyers now see a piece in 3D in a room, change size, light and color with the price updating, and hang it on their own wall with AR. Kathrin sends new pieces via WhatsApp, and import scripts add them to the shop.
For Google, every piece carries price and shipping as product data, and a dedicated sitemap reports the photos to image search. AI assistants read pieces, prices and eleven frequently asked questions directly, and robots.txt explicitly allows the crawlers of ChatGPT, Perplexity, Claude and Gemini. Purchase and contact steps reach Google Analytics and Meta after consent.
