Both my spouse and I went to a Science and Engineering university. A side effect is that various mathematical terminology now gets warped and bent to our needs.
Allow us to introduce EigenDecor!
And who said Botany, Horticulture, Geometry, Electronics, and Home Decorating could not beneficially mix?
What you see is the seed head from a South African tumbleweed, Brunsvigia littoralis, jauntily perched on the light in the corner of the living room, and being used to organize our electronic test clip leads. Viola!
The Brunsvigia littoralis are enormous South African bulbs related to the Belladonna Lilies of Southern California (actually from South Africa) and the Dutch Amaryllis sold around the holidays. We have to hand pollinate them (see http://www.littlegrove.com/2018/10/brunsvigia-pollination-time.html) to even get seed set. Once we have seeds we plant them, these take about ten to fifteen years to reach flowering size. Not the fastest plants to grow... We recently evacuated from the SCZ Complex fire, and we brought these with us, providing a rare reason to dig up our mature bulbs. The one shown below is just beginning to push up its flower bud, and is sitting on a sheet of 8.5x11" paper.
This particular bulb came to us via the University of California Botanic Garden (the one in Berkeley) semi-annual plant sale and rare plant auction in 2000. It has grown and flowered reliably for me ever since, and eventually produced a single offset bulb about five years ago.
The clip leads are not specifically interesting, though they came from a recently defunct chain of electronics and eclectica stores called Fry's Electronics. While Fry's had been declining for some time being faced with fierce competition from online retailers, the eccentricity of the early Dot-com era remained visible in their thematic stores and interior decor. For example, the Burbank store contained scenes like this inside:
I am glad to have been able to have shown my son these eccentric and fun stores before they passed into memory. We did both enjoy them.
