Adding a touch of decorative sand brightens the overall layout and creates a contrast with the dark moss and driftwood coloration.

"Substrate and ecology: growing on the trunks of trees and shrubs, such as Quercus, Heteromeles, Adenostoma, and Pinus but it is also lignicolous and often found on fence poles or unpainted wood, very rarely on rocks World distribution: distributed in coastal regions from southern Oregon southwards to northern Baja California" -

now, besides Tønsberg collection on Shaw Island, this and my previous observations seems to indicate not rare on Fidalgo Island (and probably elsewhere in Salish Sea)

Waterproof SMD Led Strip Light is a new kind of ultra bright SMD strip light, which is made of FPC very soft PCB substrate and professional circuit connection design, as well as super bright SMD 3528 or SMD5050 as a luminous body. The luminous body of Waterproof SMD Led Strip Light is symmetrical arranged on the FPC flexible PCB positive board, refined compact. After lightened, it looks like crystal. Strip light can maintain SMD light very soft, arbitrary curved, easy to install and make signs. Compare with the traditional strip light, LED Rainbow Tube, Dura-light, Waterproof SMD Led Strip Light is much more steady, reliable & safe. It is really an ideal alternative for current strip light. This product is widely used in indoor and outdoor advertising signs, hotels, department stores, show window and furniture decorative lighting.

We found this trunk for $3.87 at a junk store. The wood stripping on the edges is in bad shape and falling off in places, and the trunk needs overall tightening. It's not pretty as is, but it will be perfect for mosaic!
The slats that make up the top of the trunk have slight gaps in them. I think I'm going to fill them in and mosaic it as a smooth surface. I've been considering using rigid wrap to make that happen, but I'd love to hear any other thoughts you have on how to achieve that.
First cuts with my diamond blade dicing saw. The edges are clean, seem to be sufficient for my needs.
Thick film circuits are built on ceramic substrates and are a mix of surface mount components and printed resistors. This circuit, somewhat ironically, is part of an Argus 1 thermal imager.

Nepenthes rajah is an insectivorous pitcher plant species of the Nepenthaceae family. It is endemic to Mount Kinabalu and neighbouring Mount Tambuyukon in Sabah, Malaysian Borneo.[2] Nepenthes rajah grows exclusively on serpentine substrates, particularly in areas of seeping ground water where the soil is loose and permanently moist. The species has an altitudinal range of 1500 to 2650 m a.s.l. and is thus considered a highland or sub-alpine plant. Due to its localised distribution, N. rajah is classified as an endangered species by the IUCN and listed on CITES Appendix I.
The species was collected by Hugh Low on Mount Kinabalu in 1858, and described the following year by Joseph Dalton Hooker, who named it after James Brooke, the first White Rajah of Sarawak. Hooker called it "one of the most striking vegetable productions hither-to discovered".[3]
Nepenthes rajah is most famous for the giant urn-shaped traps it produces, which can grow up to 41 cm high[4] and 20 cm wide.[5] These are capable of holding 3.5 litres of water[6] and in excess of 2.5 litres of digestive fluid, making them probably the largest in the genus by volume. Another morphological feature of N. rajah is the peltate leaf attachment of the lamina and tendril, which is present in only a few other species.
The plant is known to occasionally trap vertebrates and even small mammals, with drowned rats having been observed in the pitcher-shaped traps.[7] It is one of only two Nepenthes species documented as having caught mammalian prey in the wild, the other being N. rafflesiana. N. rajah is also known to occasionally trap small vertebrates such as frogs, lizards and even birds, although these cases probably involve sick animals and certainly do not represent the norm. Insects, and particularly ants, comprise the staple prey in both aerial and terrestrial pitchers.
Although Nepenthes rajah is most famous for trapping and digesting animals, its pitchers are also host to a large number of other organisms, which are thought to form a mutually beneficial (symbiotic) association with the plant. Many of these animals are so specialised that they cannot survive anywhere else, and are referred to as nepenthebionts. N. rajah has two such mosquito taxa named after it: Culex rajah and Toxorhynchites rajah.

Frequently forms large clumps on surface substrate of moist rocks, or limestone slopes. Will also attach to bare granite at the tops of cliffs, under waterfalls. Endemic to Brazil.

Eggshell colour primary role is maintaining eggs crypsis and enhancing clutch survival. The nest-crypsis hypothesis proposes that predators would detect conspicuous nests before eggs, thus no selection for egg crypsis would exist. However, ground-nesting species would lay eggs that match nest background. Using artificially colored eggs, many studies have failed to show any role of egg crypsis contrary to others that found a positive relationship between clutch survival and naturally pigmented eggs. Predation risk and egg rejection are the two main behaviors tested in the context of egg crypsis, but only few studies have looked at how eggshell patterns match nest background. The aim of this study is to investigate whether females make a choice of the substrate they lay on, in an experimental design using the Japanese quail (Coturnix coturnix japonica), a species that lay brown spotted eggs and where eggshell appearance remains constant, despite female condition variations. Adult females were individually housed and given the choice of 8 plain or patterned substrates (mimicking eggshell background or spots appearance) to lay on for one week. Here I show a composite image of the eggs laid on the experimental substrates chosen by the females.

This is a broken ceramic boot given to me by one of my tennis friends.
At first I was going to cut off the high side and make a short boot but then decided to try to re-make it using chicken wire and cement based glue.
I think this might be suitable for the next Mosaic Challenge!

Spondylus versicolor Schreibers, 1793 - golden thorny oyster (public display, Bailey-Matthews Shell Museum, Sanibel Island, Florida, USA)
Bivalves are bilaterally symmetrical molluscs having two calcareous, asymmetrical shells (valves) - they include the clams, oysters, and scallops. In most bivalves, the two shells are mirror images of each other (the major exception is the oysters). They occur in marine, estuarine, and freshwater environments. Bivalves are also known as pelecypods and lamellibranchiates.
Bivalves are sessile, benthic organisms - they occur on or below substrates. Most of them are filter-feeders, using siphons to bring in water, filter the water for tiny particles of food, then expel the used water. The majority of bivalves are infaunal - they burrow into unlithified sediments. In hard substrate environments, some forms make borings, in which the bivalve lives. Some groups are hard substrate encrusters, using a mineral cement to attach to rocks, shells, or wood.
The fossil record of bivalves is Cambrian to Recent. They are especially common in the post-Paleozoic fossil record.
The golden thorny oyster is part of the Indo-West Pacific Province: "The world's largest and richest province extends from the Red Sea and East Africa across the Indian Ocean, then touches northern Australia and southern Japan to extend eastward throughout the "South Seas" to Hawaii and Easter Island. Probably 5,000 marine species are found in its shallow coral waters." [info. from museum signage]
