I bought two of them, I confess. I am fully capable of multiplying most any number times 1.6, but these struck me as valuable mostly as reminders to think of those numerical relationships more than I do. Sort of a daily affirmation when I see them in the center drawer of my desk.

So two questions: Oh, first, Phi refers to the golden triangle ratio.

1. Do you bear the ratio in mind as much as you’d like to when you’re contemplating something like drawer layout or even basic carcase size?

2. Have you bought other such gizmological excesses in hopes that it would not only help you with a certain task but also be a reminder?

I didn’t buy one but I did make one. I use them it turning and while drawing up plans. I like to make boxes and cutting boards to proportion.

It’s ingrained in me from my astrophotography. Composition is a big deal there and the golden ratio is an important tool. Same with designing the layout of my aquariums.

I don’t have the phi rules, but it’s not hard for me to remember 5:8, 1.6, and miles-to-kilometers (think about it) for a fast estimation of the magic ratio.

1) Yes … I try to come as close as possible and produces a more pleasing result.

2) Yes … I bought a Fibonacci gauge a couple of years ago, and made a set of phi calipers a few months ago.

thinking within a box is at least a reasonable starting point for going forward and looking back

Designs tend to the golden mean as an “average”, but shouldn’t dictate your functional design. Many things are built that don’t even come close to that ratio, and end up nicely in spite of it.
