Abstract modern art seems to have some things in common with some kids' art: focus on materials, color, texture, perception; and representational art may focus on symbolism rather than realistic rendering. There's also an authenticity to art that is created for personal expression without worrying what other people will think about it.

It's hard to capture three dimensional physical art in two dimensions and/or digitallly, even more so when the art is abstract. The context and interaction with the physical environment can also be important.

I actually had a similar question / comment but about plants! We have (at least) one in every room in our house and they do wonders for the space.

Not suggesting you go out and buy plants for the gaming rooms (maybe you already have) but wondering if it was a conscious decision not to have any?

Indoor plants are tricky with cats. They will chew on them, and many plants can be poisonous to them. Also keeping them watered is work, and they can create a mess if they grow in the wrong direction.

We have a lot of plants outside, though.

Makes a lot of sense. Mystery solved, thank you :)

Very nice. Well thank you for sharing your house with us, truly aspirational!
