A Forth Haiku is an attempt to mix mathematics, art, and the
Forth programming language. It resembles a texture shader,
however, the emphasis is on direct expression in the
resulting image.
The Forth program describing each Haiku is run once per pixel
over a square image. Forth cells are floating point.
Conditions return 1 instead of -1. The position is available
from the words x and y, which range from 0 to 1, which the
origin in the lower left hand corner. The haiku returns the
desired color in (red, green, blue, alpha), with alpha being
topmost on the stack. If the stack has less than 4 items
default values are assumed: red:0, green:0, blue:0, alpha:1.
Like a traditional haiku, an ideal Forth Haiku has 3 lines
of 5, 7, 5 words. Compositions which don't fit the haiku form
are either 'short' (less than 140), or 'long'.
This reminds me of zeolite-water solar adsorption refrigeration:
This paper presents some of the experimental evaluations of a prototype solar refrigerator, based on an intermittent thermodynamic cycle of adsorption, using water as refrigerant and the mineral zeolite as adsorber. This system uses a mobile adsorber, which is regenerated out of the refrigeration cycle and no condenser is applied, because the solar regeneration is made in the ambient air For the regeneration, a SK14 solar cooker is considered. The cold chamber, with a capacity of 44 liters, is aimed for food and vaccine conservation. The objective is to analyze the advantages and disadvantages of the eventual use of this refrigerator in rural regions of Peru, where no electricity is available. On the bases of the results obtained, a new prototype of refrigerator for rural regions is designed, based on the same thermodynamic cycle, but including changes in design and operation.
During the day, solar energy is used to drive water out of the zeolite.
The dry zeolite is exposed to water under low-pressure causing the water
to evaporate and be adsorbed into the zeolite. The evaporative cooling
can be used to refrigerate food without electricity.

I kept waiting for the author to mention the Fully Informed Jury Association. I somehow stumbled upon their website over ten years ago and first heard of jury nullification. It's awesome they're still at it.
