With no consideration to scale or cost:
* Codex Seraphinianus. Maybe a not huge-and-heavy edition. The edition I have is actually kinda large and
actually kinda heavy.
* a metal thing from http://bathsheba.com/, one of the mini-metal,
bam!... you have to feel it to believe it.
You don't want to put it down. You don't want to stop
staring at it. Speaking of which:
* a copy of the "FINALLY they put it all in one
book" Borges Collected [and complete] Fictions.
* a kalimba: http://kalimbamagic.com has them, tuned properly, for and by actual musicians, as opposed to tourist kalimbas that just go plink plink. I think they're pentatonic, not sure.
* a tangram set: this thing is a book plus a plain-jane wood tangram
set. Tangrams are good fun for trying to work against a pattern, or just idly making shapes on your own. Spatial perception brain-exercising stuff.
And later, you can get her a nicer tangram set anywhere in the $50 - $50,000 range.
* a piece of Southwest jewelry. The Zunis are
the best jewelers on the planet, and they sometimes make
stuff that doesn't scream "I'M FROM SANTA FE!" but instead whispers
"this is from hyperspace". A particular Zuni bracelet, a crazy one-off, is
on my short mental list of "one that got away".
I think the Zuni jeweler store (run by the Pueblo) might have a shop in Beverly Hills or Venice Beach or something– at least as of a decade ago when I saw that as one of the place-names on the side of one of their fancy fancy bags.
* As to Southwest pottery: my aesthetic leans toward occasionally Navajo, but then really jumps right at Acoma Pueblo and Jemez Pueblo stuff. You'll know the good stuff when you see it. That's just my recommendation. Also: size, quality, price (and price-where) are often independent variables.
My favorite piece in my house is a sort of discus-shaped thing, a "seed pot", maybe four inches across and one inch high, with just two lizards immaculately painted on it, no design. But I've also gone nuts and bought big complicated-patterned pots, before and since.
* Hopi black-on-black pottery– if they still make that stuff. Maybe it's all a jillion-dollar museum pieces.
* Pottery from Mata Ortiz, which is like Acoma/Jemez,
but on peyote. Not just the potter being on mescaline, you being on mescaline.
But sometimes too much mescaline. A lot too much.
* I would say to get a good sandpainting, but I once
scoured all of Albuquerque's shops and, at that moment, found two that
were at all worth even considering– buried in mountains
I have a beautiful sandpainting,
but I Knew A Guy. But maybe now all the good stuff
is out and about and online.
Getting more minimal:
* a Tibetan "singing bowl". Fun fact: you don't have to WHAM on those to get a forever-resonating effect. You can make a little tap and enjoy just the quiet forever resonances.
* a single, aesthetically immaculate, Depression glass teacup & saucer, or mug, which can be her "Well, I don't know why I use it every morning, I just do" cup. I would be partial to cobalt blue, as having a stronger presence than the other stuff, but it's an open issue.
(Why a single one? a set is vulgar and showy. A single is Just For You, and is quantitative minimalism.)
Super-bonus if it's clear uranium glass, the fancy kind that actually glows– not by radioactivity, but by absorbing ambient UV and dropping its energy into the visible spectrum, right around the color green. (The actual radioactivity you get in holding and drinking
from such a thing is lab-gear measurable, but is– supposedly–
orders of magnitude less than normal background radiation–
at any given moment, not just "well, over the course of a day...". But, ya know, fact check that.)
