Camouflage sheet inspired by octopus

Based on the camouflage abilities of octopuses and cuttlefish, engineers in the US have built a flexible material that changes colour to match its surroundings. The new design features a grid of 1mm cells, containing a temperature-driven dye that switches colour on demand. So far it only responds in black-and-white, but the team hopes that the principles of their design will have commercial and military applications.

Senior author Prof John Rogers, from the University of Illinois, said the new sheet was the fruit of a collaboration between experts in biology, materials, computing and electrical engineering.

"Animals in the natural world - particularly cephalopods: octopus, squid and cuttlefish - have really spectacular colour-changing capabilities," he told BBC News. Aug. 18

The chart for the Lunar Eclipse of April 15, 2014 drawn for Urbana, Illinois is shown here. The following points need to be noted.

The Full Moon is conjunct the star Spica, alpha Virgo. In India, this was the single determinant star of Citra, ruled by Tvastr, the heavenly carpenter, who possessed Maya, the power of making and shaping the way others see the world that is a form of magic. Its symbol was a bright jewel. The word Citra also translates as “many coloured” [1]

On the Ascendant we have the constellation of Vulpecula about which Nick Fiorenza [2] writes.

Vulpecula cum Ansere, our modern Fox with the Goose is a recent addition to the first decan of sidereal Capricorn. The Fox is indicative of the sexy, sly, cunning, covert maneuvers used to get the goose, and, as is most often the case, disguised to be something other than what it truly is.

On the MC is Saturn in tropical Scorpio aligned with the star Unukalhai, alpha Serpens. The Serpent is known for renewing its skin while Scorpio is a sign also linked to things hidden or disguised.

Progressing the chart to August 18, brings the meridian in perfect alignment with the eclipse axis with the eclipse Moon [25li] on the IC [26li]. To complete the picture on the descendant [8aq] is the star 13 Vulpecula [7aq] of the sly Fox. A Venus-Jupiter conjunction at [7le] took place on August 18 exactly opposite 13 Vulpecula and the descendant of the progressed chart.
