Triadic Colours, CYMK, Primary Colours, and Warm Colours and My Printer Solstice Prints

For the #PrinterSolstice prompt triadic colours, I choose the secondary colours orange, purple and green, which are three equidistant on the colour wheel. I was looking forward to #InsertAnInvert2024 and needing an intertidal creature.

My lino block print of two Pisaster ochraceus, generally known as the purple sea star, ochre sea star, or ochre starfish, on a bed of kelp, is hand-printed on 8" x 8" (20 cm x 20 cm) delicate white Japanese paper with bark inclusions. A common sea star, or starfish of the Pacific, it is a keystone species considered an indicator of health in the intertidal zone. Most of these starfish are purple but they can also come in orange (as shown), or ochre, yellow and brown.

These were amongst my favorite finds on the beaches of Vancouver Island.





A collection of small gel prints made with cyan, magenta, yellow and black ink, cut paper stencils, lino blocks and plant materials

For the #PrinterSolstice prompt CMYK I spent a morning experimenting with my gel plate, using paper stencils, lino blocks and plant materials and my process cyan, magenta, yellow and black inks.

For the #PrinterSolstice prompt primary colours, I thought I would play with adding yellow and red to a cyanotype (which are in tones of blue of course). I decided to return to my idea of contrasting a fractal Sierpiński triangle and the naturally occurring fractal shape of a fern leaf. The Sierpiński triangle (also called the Sierpiński gasket or Sierpiński sieve) is a fractal equilateral triangle, subdivided recursively into smaller equilateral triangles. It's a self-similar sets—that is, it is a mathematically generated pattern that is reproducible at any magnification or reduction named after the Polish mathematician Wacław Sierpiński. This was a decorative pattern many centuries before Sierpiński. I made a cyanotype of a fern leaf and used a gel plate to add a red circle. I lino block printed the yellow Sierpiński triangle.

And for the final prompt warm colours, I looked ahead once again to prompts for #InsertAnInvert2024 and decided I needed to make a true crab.

 My hand-printed red frog crab (Ranina ranina), also known as a spanner crab or Huỳnh Đế crab, is hand-printed on Japanese kozo (or mulberry) paper 8" x 8" (20.3 cm x 20.3 cm) square. This crab is found in tropical and sub-tropical waters offshore Australia, the Philippines, Vietnam, the east coast of Africa, through the Indian ocean to  the Pacific offshore Japan and Hawai'i. It is the sole known member of its genus and it is fished for its meat. The 5.9" (15 cm) crabs live in 10 to 100 m (33–328 ft) or water, where they bury themselves in the sand during the day and hunt bottom-dwelling fish. Known as "frog crabs", on account of their elongated carapace and frog-like appearance. Their claws are modified into tools for digging, and the body is a rounded shape that is easy to bury in sand. Unlike most other true crabs, the abdomens of raninids are not curled under the cephalothorax, so they are a little unusual looking.

Ranina ranina is a regional specialty in some regions of the Philippines where it is known as curacha. It is generally eaten steamed as halabos, or cooked in coconut milk as ginataan. In Vietnam the species is named as "Huỳnh Đế crab", literally means "emperor crab" as it has been a favorite high-ranked cuisine of historical Vietnamese monarchs hailed "monarch of all the crab".

Space Jellyfish Fractal Triangle Quilt

spacejellyfishtrianglequilt1

Yes, you read right. Reynardin seems to have given me the plague her cold, but I have managed to sew with a fever this week. See, I had some completely awesome (if I do say so myself) space fabric printed with imagery I downloaded from NASA (credit: NASA/courtesy of nasaimages.org). They kindly keep the vast majority of their photography open source and you can use it, though they appreciate a credit. See? I did too need more fabric.

So, I planned this quilt as a giant fractal Sierpiński Triangle, with nested lino block printed fractal Sierpiński Triangles). Also, some of the downward pointing triangles which by default are space imagery are replaced by my block printed jellyfish on dark blue fabric). I carefully arranged the triangles so that areas with nebulae were nearby one another (nebulous areas? nebularful? nebulicious?) and the starry, mostly dust-free regions were near one another. So it's space, jellyfish, fractal triangle FTW. This is just the quilt top, so this is still a work in progress. I bought some glow-in-the-dark thread for the actual quilting, bwhahaha!

I'll get some proper photos of it when it's complete.

Fractal Geometry II on the Front Page (again!)



I guess triangles are the thing. It's weird though:
a) this piece is a little odd anyway, and not strictly representative of what I do
b) if it's going to be on the front page of etsy on June 15 and August 24th, why not choose Fractal Geometry I just to mix it up a bit.

So, today I will spend in the parking garage, spooling the winch. So far, getting frustrated diassembling the power connector (which doesn't match our 400 V supply, so we hard-wire it), I chopped it off. Then, as I stripped the wires, I recalled that the last time I re-terminated a winch cable, I ended up at Royal Jubilee Hospital in Victoria, getting stitches.

Front Page Fractal Geometry

Fractal Geometry II on the Front Page

'Fractal Geometry II' on the front page

One of the leaf prints + lino prints of a fern leaf and Sierpiński Triangle just made it to the Etsy Front Page (in the bottom right corner) - much to my surprise.

I made that for an MSOE challenge on fractal geometry last September. I debated relisting it, and thought I should do something with the Sierpiński Triangle block. When I visited Etsy the funny thing is that with the new aspect ratio, at first I only saw the top row or so, and thought to myself, 'oh, are triangles still the thing?' and then I scrolled down and actually clapped my hands when pleasantly surprised.

fractal geometry

You were dying to know why I've been hunting ferns, right?

For the month of September, 2009, the MSOE challenge is 'Fractal Geometry'. Fractals are self-similar: their parts mimic (more-or-less) the whole. Some of the exotic species within this mathematical family have precise familiar shapes, like the simplest rectilinear object you could imagine, the triangle. Others have organic lines like coast lines or plants. The fern is a stereotypical example; oblong leaves with branch off of veins which in turn branch off of other veins, in a self-similar manner.

In this mono print, I am comparing and contrasting the aspect of self-similarity, by combining a block printed Sierpiński Triangle (the holes in which could in theory continue ad infinitum, but being human, there is a practical limit to what can be carved) and a printed fern leaf.

Then, I did it again:
