Surfacing quickly to let you know about this cool product! My client discovered this while brainstorming ideas for large scale art. Ixxi will take your photos and images and print them on square cards, which you attach together and hang. My favorite look is when a photo is enlarged this way, but you can also do a collage of images (baby pictures, travel pictures, you name it). And if you're in the Netherlands, you have access to a collection of printed works.
In general, this seemed like a cool way to get an affordable piece of large artwork (especially with no extra framing costs!). I'm filing this away for future reference.
