Artichoke Zoetrope

zoetropeWhich is a new thing from John Edmark, who makes amazing 3D printed Zoetropey devices.

For which he has kindly made an instructables page.

I’ve been following his stuff for a while now – was hoping he’d try the zoetrope thing with a pinecone or a sunflower or something – but if you’ve got an artichoke, the solution to every problem looks like an artichoke.

137.5ยบ is the golden angle… which I haven’t really looked into a whole lot. This is the angle-spacing between petals etc… I seem to remember reading somewhere that this angle in sunflowers minimises the elastic tension between the seeds… I think in plants, it also maximises the amount of light hitting the plant as a whole. Phyllotaxis.

It’s quite interesting how the solutions to really complex computational problems can precipitate naturally out of really simple mathematics. Simplicity is its own reward… especially if you don’t have an actual brain or whatever. Do plants have brains? Not noticeably – so how are they doing this maths? It’s a conundrum.

(oh yea – if you’re thinking of using ‘Artichoke Zoetrope’ as a band name, or some sort of boutique startup company name, or the name of your child etc… don’t. Just because it hasn’t been done yet, doesn’t mean it should be.)

Wake me up when it’s 2020

Okay, it's 2020 now I guess. [br]I've been making Golden Mean Calipers for about 10 years now. [br]In 2019 I wrote 2 blog posts... that's not enough to achieve the various purposes of writing blog posts, among which are: [br]- to learn what you think [br]- to show people you're still alive [br]- to show google (et al) you're still…

Golden Mean Caliper Comparison Chart

I thought it might be useful for people to be able to compare all the calipers on the one page, so I made a comparison chart.

Demo of Golden Ratio in Artistic Composition (fairly disorganised)

Over the years, I've built up a collection of Golden Ratio Calipers... and I decided it might be quite useful for people if I made a video comparing them. Some of them are really good - some terrible. So I set up my camera... and found that my video-space looked a bit bare... needed a painting. So I decided to…

Why The Golden Ratio Works For Flowers

Fairly amazing video going into the maths of why flowers (and pine-cones, relative leaf positions etc) are so often based fibonacci numbers. https://www.youtube.com/watch?v=sj8Sg8qnjOg And it's fairly amazing because I actually understood it. It's been a loooong time since I tangled with quadratic equations, but (on the 2nd watch) this did actually make sense to me. I always thought that with…

Limited Run : Neon Colour Range

https://www.youtube.com/watch?v=zoPqpqB6er0 I was tinkering with these colours a while back... and then someone with exceptional taste and style made a big order for a whole range of coloured ones... and every one was all "ooh!!!" So I made some for the local art gallery - and they all sold as well. So I made enquiries about getting a lot more…

New Product Videos

I'm putting together a series of product videos... one for each of the 10 or so different calipers that I make. [br]They will all look kindof the same... they're mainly for embedding in shop pages and so on. Because they'll all look kindof the same, I've made a separate youtube channel so subscribers don't lose their minds with boredom. https://youtu.be/qvXxBQCkF30…
