Question: What type of symmetrical-drive structure with perfectly geometric shapes does S.M. Ganapathi create?

Context paragraphs:
Hindu temple architecture: The Hindu temple architecture is an open, symmetry-driven structure, with many variations, on a square grid of "padas", depicting perfect geometric shapes such as circles and squares.

S. M. Ganapathy: Sattanatha Muthiah Ganapathi, popularly known as S. M. Ganapathi sthapathi, is an Indian architect and builder (sthapati) of traditional Hindu temple architecture.  He was known for his contribution in saving 48 archaeologically important temples near the Nagarjun Sagar reservoir from submergence.  "Orirukkai Manimantapam", "Ramalayam" and "Kalyana Mandapam" at Bhadrachalam and the "Mahamantapam" of the Badrinath Temple are some of his notable creations.  The Government of India awarded him the fourth highest civilian award of Padma Shri in 1990.

Patterned ground: Patterned ground is the distinct, and often symmetrical natural pattern of geometric shapes formed by ground material in periglacial regions.  Typically found in remote regions of the Arctic, Antarctica, and the Australian outback, but also found anywhere that freezing and thawing of soil alternate; patterned ground has also been observed on Mars.  The geometric shapes and patterns associated with patterned ground are often mistaken as artistic human creations.  The mechanism of the formation of patterned ground had long puzzled scientists, but the introduction of computer-generated geological models in the past 20 years has allowed scientists to relate it to frost heaving, the expansion that occurs when wet, fine-grained, and porous soils freeze.

Patchwork: Patchwork or "pieced work" is a form of needlework that involves sewing together pieces of fabric into a larger design.  The larger design is usually based on repeating patterns built up with different fabric shapes (which can be different colors).  These shapes are carefully measured and cut, basic geometric shapes making them easy to piece together.

Geometric separator: A geometric separator is a line (or other shape) that partitions a collection of geometric shapes into two subsets, such that proportion of shapes in each subset is bounded, and the number of shapes that do not belong to any subset (i.e. the shapes intersected by the separator itself) is small.

Day shapes: Day shapes are mast head signals visually indicating the status of a vessel to other vessels on navigable waters during daylight hours whether making-way, anchored, or aground.  These signals consist of a set of simple geometric shapes: "ball, cylinder, cone," and "diamond" that are displayed, hung from a mast, in a prescribed manner to indicate a vessel's operational status; some of these signals may be somewhat involved.  The meanings of the shapes are defined by the International Regulations for Preventing Collisions at Sea (ColRegs).

Geometric set cover problem: The geometric set cover problem is the special case of the set cover problem in geometric settings.  The input is a range space formula_1 where formula_2 is a universe of points in formula_3 and formula_4 is a family of subsets of formula_2 called "ranges", defined by the intersection of formula_2 and geometric shapes such as disks and axis-parallel rectangles.  The goal is to select a "minimum-size" subset formula_7 of ranges such that every point in the universe formula_2 is covered by some range in formula_9.

Table of Contents (Enochs): Table of Contents is a sculpture designed by the American artist Dale Enochs.  The sculpture is made from limestone and was commissioned by Joseph F. Miller.  The sculpture is located across the street from the IUPUI campus, at the N.E. corner of W Michigan St and West St, and sits in front of the Miller Centre in downtown Indianapolis, Indiana.  "Table of Contents" displays four geometric shapes, which include a circle, triangle, crescent and square.  These shapes sit atop a table with four legs, all pieces are carved from limestone.  The shapes as well as the table are carved with curved lines which run up and down the sculpture, but some areas are left smooth.  The square has "terrae" written on the side.  Terrae means extended mass land.

List of two-dimensional geometric shapes: This is a list of two-dimensional geometric shapes in Euclidean and other geometries.  For mathematical objects in more dimensions, see list of mathematical shapes.  For a broader scope, see list of shapes.

Incredibots: IncrediBots is a physics simulation game and series produced by Grubby Games and was later purchased by Big Fish Games.  It uses the Box2D Physics Engine, which allows objects created in a simple click and drag fashion to interact realistically.  Users can create basic geometric shapes such as triangles, rectangles, and circles, and then connect them together using different types of joints.  The three basic kinds of joints are fixed joints (which permanently connects two shapes together to form a larger solid shape), rotating joints (which allow rotational movement), and sliding joints (which give objects one-dimensional linear movement, much like a pneumatic piston).  Once combined with shapes, these joints form what are known as "'bots", "robots", or "IncrediBots".  One other kind of joint, thrusters, are like rocket engines.
