STRUCTURES is a series of generative art pieces the explores the constructions of our world by taking photographs of man-made and natural structures and placing them into a new structure. This process semi-randomly fragments and rearranges the photographs into a grid of my design. I'll often run the images through this process several times, using various grid structures along the way.

Light curves in beautiful colors - the rational mind is more prone to squares and triangles.
Structure Synth terminates the recursion if the number of objects is greater than the given threshold ('set maxobjects ...') or if the recursion depth becomes greater than the maximum depth ('set maxdepth ...'). It is also possible to set a maxdepth for an individual rule ('rule R1 maxdepth 5').
I've added two new rules for controlling the termination.
'set minsize {size}' and 'set maxsize {size}' allows you to specify how large or small a given object can be before terminating. The 'size' parameter refers to the length of the diagonal of a unit cube in the current local state. (The initial coordinate frame goes from (0,0,0) to (1,1,1) and hence has a diagonal length of sqrt(3)~1.7). It is possible to specify both a mix and a min size. The termination criteria only stops the current branch - if other branches are still within a valid range, the will be continued.
This is very useful for preventing Structure Synth from creating boxes which cannot be seen anyway or from growing without bounds.
The image shows the same structure at three different minimum size tresholds.
Example script (requires a post-version 0.9 of Structure Synth!):
set minsize 0.8 // or 0.4, or 0.2
set maxdepth 600

Yaxchilán, Structure 33
Yaxchilan is an ancient Maya city located on the bank of the Usumacinta River in what is now the state of Chiapas, Mexico. In the Late Classic Period, Yaxchilan was one of the most powerful Maya states along the course of the Usumacinta, with Piedras Negras as its major rival. Architectural styles in subordinate sites in the Usumacinta region demonstrate clear differences that mark a clear boundary between the two kingdoms.
Yaxchilan was a large center, important throughout the Classic era, and the dominant power of the Usumacinta River area. It dominated such smaller sites as Bonampak, and had a long rivalry with Piedras Negras and at least for a time with Tikal; it was a rival of Palenque, with which Yaxchilan warred in 654.
The site is particularly known for its well-preserved sculptured stone lintels set above the doorways of the main structures. These lintels, together with the stelae erected before the major buildings, contain hieroglyphic texts describing the dynastic history of the city.
Structure 33, in the Central Acropolis, has been described as a masterpiece in stone and was probably dedicated in 756 by Bird Jaguar IV. The structure overlooks the plaza and the river and would have been prominent to river traffic in the 8th century. It has plain lower walls with three doorways, each of the which supports a well preserved lintel (Yaxchilan Lintels 1 to 3). In the centre of the back wall of the structure, opposite the central doorway, is a niche containing the headless sculpture of a human figure, probably Bird Jaguar IV himself. The roof of the structure is largely intact, including a sloped roof supporting a frieze and a well preserved roof comb. There are niches in both the roof comb and the frieze, the niche in the roof comb contains the remains of a sculpted figure. Tennons on both roof sections once supported stucco decoration. Leading up to the front of Structure 33 from the plaza is a stairway, the top step of which is sculpted, this step is known as Hieroglyphic Stairway 2.
