Websites like this were our main projects.
It was easy to make them team projects, they asked us to split between programmer and designer.
The designer had to create the assets.
We had a photo lab and the designer was sent into town to take photos.
We weren't allowed to use stock images, which would have speeded up the process.
However, it was still relatively simple for young adults to create the elements.
AI is cool, and yes, it will make everything faster.
But I don't think the wall here was feasibility, it's more that the skeuomorphism trends ended and the market was saturated with highly dynamic interactive websites thanks to Flash making them easy to manage.
So the trends stopped.
It's nice to see it coming back, it was a lot of fun creating them.
