Gewgaws

This is a list of Gewgaws made by Cat's Eye Technologies, listed in alphabetical order. For more information on these Gewgaws, see below.

The distinction between a Gewgaw and an Automaton or even a Game is not always cut-and-dried, so if you can't find what you're looking for here, try those lists as well.

A circle-based time-lapse space-filler.

Colourring

• inception date: 2016
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: colourring.js
• online @ catseye.tc

An attempt to make some generative art with as much colour contrast as possible, or at least, a lot of colour contrast.

Eine kleine Glitchfraktal

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: eine-kleine-glitchfraktal.js
• online @ catseye.tc

A simple fractal (each rectangle contains four smaller rectangles) with colour variance and configurable glitching.

Erratic Turtle Graphics

• inception date: ca 2018
• reference distribution: Erratic Turtle Graphics distribution
• reference implementation name: erratic-turtle.js
• online @ catseye.tc

It's turtle graphics, except there's a small margin of error. You might ask for "Turn right 90 degrees" but you might get only "Turn right 89.91 degrees".

It uses a faint pen, so if you repeat the drawing instructions many times over, you get a nice pencilly noisy effect.

Fibonacci Spiral

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: fibonacci-spiral.js
• online @ catseye.tc

A spiral made up of semicircles with proportions in the Fibonacci sequence.

Fingerspelling

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: fingerspelling.js
• online @ catseye.tc

A simple interactive entertainment, intended to be experienced on a touchscreen device.

This is most certainly a gewgaw. It should provide you about 20 seconds of entertainment, give or take.

Heronsis hermnonicii

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: heronsis-hermnonicii.js
• online @ catseye.tc

An animated "plate" depicting a proto-cohort of Heronsis hermnonicii.

Warning: the following may contain tedious and/or glib background and/or analysis.

Casting a negative space of knowledge. Calling itself a "plate" frames it as a work of learning, like some kind of 19th-century anthropology text. Yet it only raises questions — what are these entities? what kind of world do they inhabit? what are they protecting? who is Clarkson? — without providing answers, leaving it up to the observer to either imagine their own answers, or decide that answers to these questions are not necessary.

Plus it's fun to click on the red balls.

Hirsute Miasma

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: hirsute-miasma.js
• online @ catseye.tc

Your web browser is burdened by the sins of its ancestors and their shower drains.

Hypongtrochoid

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: hypongtrochoid.js
• online @ catseye.tc

"Hypongtrochoid" is a portmanteau of hypotrochoid (as popularized by Spirograph) and Pong (as popularized by, well, Pong.)

Kolakoski Kurve

• inception date: 2016
• reference distribution: Kolakoski Kurve distribution
• reference implementation name: kolakoski-kurve.js
• online @ catseye.tc

This is a geometric interpretation of the Kolakoski sequence (also known as the "see and say" sequence) using turtle graphics: 1 means turn while 2 means go forward (roughly speaking.)

Latcarf

• inception date: Feb 2018
• reference distribution: Latcarf distribution
• reference implementation name: latcarf.js
• online @ catseye.tc

Most recursive fractals are created top-down: start with a big thing, add some smaller things to it, add some even smaller things to those things, etc.

I was curious about what it would be like if a fractal was generated bottom-up: start with many small things, connect them to larger things, then connect those to even larger things, etc.

This is the result of implementing that method.

Lexeduct

• inception date: Apr 2015
• reference distribution: Lexeduct distribution
• reference implementation name: lexeduct-browser.js
• online @ catseye.tc

A "livetextmangler" — an online tool which transforms text. As you select different filters to apply to the input, the output is updated in real-time. Can also be used on the command-line.

Markov Font

• inception date: Apr 2016
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: markov-font.js
• online @ catseye.tc

Uses a 2D Markov chain to generate new glyphs from a character set.

Maze Clouds

• inception date: Sep 2017
• reference distribution: Maze Clouds distribution
• reference implementation name: maze-clouds.py
• online @ catseye.tc

A simple generative technique to generate mazy, cloudy forms.

Multicolouralism

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: multicolouralism.js
• online @ catseye.tc

Animated op art: an interactive bleeding of colours.

Noise to Signal No. 1

• inception date: Apr 2015
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: noise-to-signal-1.js
• online @ catseye.tc

A generated animation involving randomness and not-so-much randomness.

Pixed-Point

• inception date: May 2015
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: pixed-point.js
• online @ catseye.tc

A process by which an image containing some text is constructed. The process does not always terminate, but when it does, the image it produces is self-describing.

Prairie

• inception date: 2012
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: prairie.js
• online @ catseye.tc

An animated impressionistic depiction of the prairies.

I composed this while still in Winnipeg and still learning about the capabilities of <canvas> — something about the wind and the wheat... The background is a public-domain drawing of a grain elevator taken from Wikimedia.

Progression

• inception date: 2012
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: progression.js
• online @ catseye.tc

Animated op-art exhibiting a moiré effect.

A real eye-tickler. This was one of the first bits of <canvas> code I ever wrote; I essentially wrote it by accident — it wasn't quite what I meant, but I liked it, and kept it. For me, in Firefox, it starts getting interesting around 100 iterations, and starts stopping being interesting around 1550. In Chromium, you can still see some activity at about 2000 iterations, but it's very faint thereafter.

Radialjective

• inception date: 2013
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: radialjective.js
• online @ catseye.tc

An animated mathematical function, depicted in four different ways.

Rigamaroads

• inception date: 2016
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: rigamaroads.js
• online @ catseye.tc

Randomly-assembled street map or circuit or something similar to these.

Semicircle Jam

• inception date: May 2016
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: semicircle-jam.js
• online @ catseye.tc

A path made of semicircles.

Spadgets

• inception date: Jul 2016
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: spadgets.js
• online @ catseye.tc

An attempt as making generative asemic writing (well, printing) that was going alright and then I started to go a little overboard and then it no longer looks much like writing. There was another idea here that remains unexplored, namely, constructing a Markov model in one context (say, words of a text) and extracting it and using it in an unrelated context (say, when building a spadget.)

Tentacles, Undamped

• inception date: ca Feb 2014
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: tentacles-undamped.js
• online @ catseye.tc

A simulation of undulating tentacles. It starts off alright, but soon starts doing things real tentacles never do, because real tentacles have damping.

Text Uniquifier

• inception date: Nov 2014
• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: text-uniquifier.js
• online @ catseye.tc

An online tool/amusement where you paste in some text and it displays the text with repeated words removed.

• reference distribution: HTML5 Gewgaws distribution
• reference implementation name: the-frame.js
• online @ catseye.tc

An interactive exploration of the concept of The Frame in art, based on words and 'do by Frank Zappa.

About these Gewgaws

In Chrysoberyl parlance, a gewgaw is the digital version of a bagatelle (music) or a doodle (visual art). It almost always involves visuals (usually animated), sometimes audio, and occasionally interaction.

A gewgaw need not be implemented in HTML5, but most of Cat's Eye Technologies' gewgaws are, and you can can experience them here, online, right in your web browser.
