The indexed project record reports a completed edition of 390 of 1000000 invocations, runtime p5@1.0.0, and the official description: This project opens on November 22nd at 2pm ET/1pm CT and closes on December 1st at 2pm ET/1pm CT.  # Yuccas and Boxes One of the things I took away from my summer trip to Marfa was the need to spend more time absorbing my surroundings and thinking back on my experiences. Witnessing the vast fields of yuccas flowering simultaneously and watching the sunrise over Judd's 100 untitled works in mill aluminum are two specific moments that will never leave my memory. Combining these two sensations resulted in generative arrangements of yuccas and boxes. ## Edge of the desert The city of Marfa is on the northeast side of the Chihuahuan desert. The weather is dry and hot in the summer. Plants that grow naturally in the region, like the yucca, have adapted well to the harsh conditions. ## Soaptrees In the Americas, there are a lot of different types of yucca. The type of yucca that grows in and around Marfa is called yucca elata, which is also known as the soaptree yucca. These yuccas grow very slowly, only about an inch per year. Yucca elata doesn't always bloom, but when it does, the flowers come out between May and June. ## Sunrise at Chinati The Chinati Foundation is a museum in Marfa based on Donald Judd's ideas. The focus is on works that have a strong connection to the land around them. Sometimes a special event called \"Sunrise at Chinati\" is held at the museum so that people can see the many works in the golden light of the morning sun. # An SVG is available! The SVG is a fully scalable resolution agnostic version of the image. To access the SVG press the \"p\" key and the SVG will automatically download.

Atlas position is a catalogue ordinal and is not the on-chain project ID.

The script was read in full; it was not executed in this research session. [^S03]\n\nThe stored generator is 34717 bytes, SHA-256 91d6e22919b560d3ecc6ae2633f355e6a543e0639ac5235afbc849ee22420cee, runtime p5@1.0.0. Detected source markers: setup, draw, noLoop, createCanvas, keyPressed, tokenData, hash. Named functions include R, RR, average3, boxToBB, breakLinks, canvasAsBB, combineBB, contour, createFlowerPower, createGrid. tokenData.hash is read in source. Output then follows the drawing path those functions implement. Token 0 observation: Inspected media-proxy PNG is 1800x2400px, mid-tone and muted or near-neutral (mean RGB 145,144,137).

Time and interaction behaviour in code is: Source contains noLoop. The inspected PNG is a finished still. Live motion was not stopwatched. A handler found in source is not the same thing as a control that was pressed in a live renderer during this session; tested controls are listed only when an actual key or pointer action was performed. [^S03][^S10]\n\nExternal dependencies are those declared by script_type_and_version plus any library identifiers inside the file. Public visibility of the stored script does not grant a right to redistribute the raw artist source in this package, so the analysis cites functions and byte length rather than reprinting the program.
