A Semester of Pottery
These are the results of an amazing, adventurous semester of ART 148 - Fundamentals of Pottery. I can't wait to do more! Clearly my photography still needs some work, apologies in advance. (click an image to view a bigger version--bigger not guaranteed to be better).
Title: "my new favorite mug"
Clay: Long Beach, cone 10
Glazes: Jed's green inside, purple eggshell matte outside. Transparent over royal blue and cactus green underglazes for the badge.
Character meaning: "tree"
Key facts learned:
1. Throwing pottery is an activity of uncanny delight.
2. What I imagine coming out of the kiln and what actually comes out of the kiln are two very different things.
Title: "catfish mug"
Glaze: Transparent
Key facts learned: Underglazes with similar colors must be layered thick for good contrast; glaze applied too thick leads to crazing.
Title: "unbelievabowl"
Clay: Long Beach, cone 10
Glazes: rutile blue inside, angel eyes outside.
Key fact reinforced: the kiln is magical in its ability to defy expectation (true with every piece yet completed).
Clay: Long Beach, cone 10
Glazes: Coleman's purple over blue speck
Key fact learned: Remove both lifters at the same time and a clean split will develop with drying.
Title: "pretty ugly bowl"
Clay: Long Beach, cone 10
Underglaze and slip: Voulkos blue outside applied with a skunk-hair brush, dysfunctional violet inside.
Glazes: Non-iron blue celadon airbrushed base with rutile blue on the rim and Coleman's purple on the base.
Title: "Jupiter bowl"
Glazes: Miami Beach over transparent.
Key facts learned: Vaporized copper can migrate amongst items in the kiln, lending unexpected color, though more exploration is necessary to see if that's what happened this time. The coldest part of the kiln is at the top; temperature and the rate of change thereof contribute significantly to the outcome of a piece. Bubbles can form in the glaze when overheated, and certain things such as oil transferred from fingers can cause the glaze to run away from a spot thus leaving it bare. (yes, this was an educational bowl).
Title: "impractical pitcher"
Clay: Long Beach, cone 10
Glazes: Coleman's purple over angel eyes.
Underglaze: cactus green
Glaze: lion yellow (pictures taken pre-application)
Comment: remains to be fired.
Title: "dish for pickles the cat"
Clay: Long Beach, cone 10
Glazes: rutile blue undercoat, teadust black inside, Coleman's purple outside.
Title: "Tildy mug"
Clay: Long Beach, cone 10
Underglaze: pink around rim, handle, foot and symbol.
Glazes: Coleman's purple inside, angel eyes over rutile blue on the symbol side, with Farrell 2-A on the handle side.
First Mug

First Bowl - One Pound

Key fact learned: Remove both lifters at the same time and a clean split will develop with drying.
Third Bowl - Three Pounds
Title: "pretty ugly bowl"
Clay: Long Beach, cone 10
Underglaze and slip: Voulkos blue outside applied with a skunk-hair brush, dysfunctional violet inside.
Glazes: Non-iron blue celadon airbrushed base with rutile blue on the rim and Coleman's purple on the base.
Fourth Bowl - Black and White
Glazes: Miami Beach over transparent.

Extra-curricular 1 - Food Dish
Clay: Long Beach, cone 10
Glazes: rutile blue undercoat, teadust black inside, Coleman's purple outside.
Extra-curricular 2 - Tea Mug
Clay: Long Beach, cone 10
Underglaze: pink around rim, handle, foot and symbol.
Glazes: Coleman's purple inside, angel eyes over rutile blue on the symbol side, with Farrell 2-A on the handle side.

Spectrogram of a Swept Triangular Wave
I was going about in my typical atypical way and by chance did discover a very attractive fractal that is the frequency spectrogram of a swept triangular wave. I made this quick and dirty animation of a ping-pong zoom of it:
This was done with Audacity, GIMP, and NCH Tone Generator, all of which are free--my thanks to everybody who ever contributed code to any, it should be known that my thanks is an exponential function, for anybody who may have contributed to more than one. Also, thanks to anybody who understands any of what I write.
It should be noted that a number of other interesting fractals can be generated, depending on the wave type and the sweep.

Iteration
I've added threaded scene capture to my ray tracer so that I can make animations. Combine this with a map of the Mandelbrot set, and you can do things like this:
This animation also uses the reflection model of the ray tracer to complicate things a bit near the end, as you may have noticed.
One of the first animations I got out plays like a short film:
This result was accidental, I had meant to iterate by floating point values but was casting to integers at the wrong place; as it turns out, some interesting things happen around integral values.
If that's a short film, this might be a summary of that film:
note that I practically always display the set with a basis orientation contrary to convention--this is mainly because the blobs lend themselves more readily to anthropomorphizing than the alternate, and are thus naturally more aesthetic.
The following shows the set lights off and lights on:
In fact, the only difference between the two (IIRC) is that for the second I added an additional light to the ray tracer.
