Where can I find some wall art like this?

[BrimminUp]

This wall art was behind a guy being interviewed on tv (who I've snipped out of the centre). Does anyone know what search terms I could use to find something similar to buy online? I tried using Google Lens, but no luck.

Hopeful bump?

Tate modern shop?

Etsy is usually a good bet for this sort of thing. If you search for "abstract wall art", something you like will probably come up.

Maybe try abstracthouse.com/

But I wondering what the style of tiling several square pictures together like this is called - is it a mosaic or does it have another name? I know 3 panels is a triptych so I'm wondering if this style has a name too.
