Crucifère de 4-12 cm aux feuilles (1-1,5 cm) toutes en rosette, les hampes terminées par une grappe courte. Fleurs blanches (3-6 mm de large) aux pétales (1-3 mm) profondément bifides et plus longs que les sépales. Etamines dépassant le stigmate. Grappe fructifère à pédicelles grêles et silicules (6-10 mm) latiseptées (valves larges et plates à cloison large), elliptiques à obovales ou suborbiculaires.
Autre nom français : Erophile (de eros : printemps et philos : ami, son ancien nom de genre). Espèce polymorphe aux microtaxons autogames, pionnière et ubiquiste, en réalité pré-vernale, psammophile à saxicole, caractéristique du Cystoptéridion fragilis (cf. H des Abbayes, F Couplan, Guide des groupements végétaux de la région parisienne et P Jauzein).

Aragonite from Morocco.
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 6100 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The carbonate minerals all contain one or more carbonate (CO3-2) anions.
Aragonite has the same chemistry as calcite - it is calcium carbonate (CaCO3). However, aragonite has a different molecular structure - the atoms are packed differently. Different minerals having the same chemical formula are called "polymorphs" (another good example is graphite and diamond - both are carbon, C).
Unlike calcite, aragonite forms crystals in the orthorhombic class. Many aragonite crystals are acicular (needle-like) or pseudohexagonal. The latter is the result of six orthorhombic prisms growing parallel to each other. The sample seen here is a radiating cluster of pseudohexagonal, cyclic-twinned aragonite masses.
Aragonite is slightly harder than calcite, at H=3.5 to 4, occurs in many colors, and easily bubbles in acid. Aragonite is a little bit heavier than calcite, due to closer packing of atoms.
Most modern seashells and coral skeletons are composed of the aragonite. Whitish-colored lime sand beaches in the world are aragonitic. Occasionally, "whitings" are seen in shallow, warm ocean environments. Whitings (cloudy, milky seawater) turn out to have numerous tiny, hair-like needles of aragonite.
In the rock record, aragonitic or aragonite-rich sediments convert to calcite over time. Cenozoic-aged carbonate sedimentary rocks are often aragonitic. Mesozoic- and Paleozoic-aged carbonates are almost always calcitic. Many ancient fossils have had their aragonitic shells dissolved away. Ancient shells that were originally calcitic are often still well preserved.

Agatized coral from the Tertiary of Georgia, USA.
Parts of Georgia and Florida are known for having geodized, agatized corals. The original coral skeletons were composed of aragonite (CaCO3, calcium carbonate), a polymorph of calcite. The fossil corals have since been silicified and geodized, resulting in chalcedony-lined cavities / vugs.
Thie example is remarkable for its rainbow colors.
Stratigraphy: supposedly from marine sedimentary rocks in the Hawthorn Group, Tertiary
Locality: undisclosed / unrecorded site attributed to the Withlacoochee River, near the Georgia-Florida border, far-southern Georgia, USA

I decided what my Teapotty! needed was some RGB LED heart indicators to show when and where Teapotty had moved over 180 degrees, so I added some BlinkMs (addressable RGB LEDs), some more code and then made some polymorph hearts.
Teapotty! is a teapot sitting on a servo which takes readings from a magnetometer which is influenced by neodymium magnets in a cup. The magnetometer takes the reading from the north position, plays a bit of something similar to the Tetley Tea tune and then moves to a new position - where the teacup moves to.
Teapotty! is an interactive electronic teapot I've constructed for the Chi-TEK tea party event & exhibition of tech teapots at the V&A in Sept 11.

About the Artist:
"quadrapop Lane has been in SL for over a year now - building, running a gallery and now a sim dedicated to the content creators of SL.
The avatars worn by quadrapop are varied and as the profile says.... "I am a polymorph so don't expect me to look like this pic in my profile... I could be male, female, animal or mineral... and sometimes I'm just a cloud of particles...." So if you dont recognise the AV with quadrapop Lane above it that is probably why.
Hir SL artworks have a distinctive style... rainbows feature as do circles and spheres in many forms... there is no social commentary... this is pure exploration of the possibilities of the SL prim building system for abstract ends. Some have described hir texture use as inspired... and it is true that the textures on the sculptures are integral to the work's success.
When you enter a space created, or decorated, by quadrapop you are well aware that you are no longer in Kansas (nor anywhere else on Earth) - this is purely SL.
The objects will morph without changing shape. The lighting will change their mood and sometimes their meaning, so play with your environment settings. Glow, alphas and flexi prims are all essential apsects of most of these works."
A couple of weeks ago Museums and Public relations department had an away day at the Institute of Making.
