Floppy Drive Songs

Yes, these are the 3.5-inch floppy disk drives computers used to have, but now they can be used to play entire songs, thanks to a special circuit that vibrates a floppy disk head at particular frequencies to make music. In the early 1980s, a number of manufacturers introduced smaller floppy drives and media in various formats. Companies eventually settled on a 3.5-inch floppy disk, similar to a Sony design, but improved to support both single-sided and double-sided media, with formatted capacities generally of 360 KB and 720 KB respectively. All 3.5-inch disks have a rectangular hole in one corner which, if obstructed, write-enabled the disk. The HD 1.44 MB disks have a second, unobstructed hole in the opposite corner which identifies them as being of that capacity. Continue reading for more.

Avenue of the Baobabs

These trees may look like they are straight from Disney's upcoming live-action Jungle Book movie, but it's just Avenue of the Baobabs, which line the dirt road between Morondava and Belon'i Tsiribihina in western Madagascar. Its striking landscape draws travelers from around the world, making it one of the most visited locations in the region. Baobab trees, up to 800 years old, known locally as renala (Malagasy for "mother of the forest"), are a legacy of the dense tropical forests that once thrived on Madagascar.

The Writer Automaton

The Writer automaton (self-operating machine or robot) was the inspiration for the principle character in the Martin Scorsese's Hugo movie. This 240-year-old machine, comprised of 6000 parts, works by using a crank to wind up the mainsprings before the head as well as eyes start moving for life-likeness, following its own hand movements as it writes. That's not all, the automata even dips its quill into an ink bottle between words. What makes all of this possible are 40 cams with three cam followers that read their shaped edges and translate them into movements of the boy's arm. Controlling them is a large wheel or 'system disk', made up of letters that could be removed, replaced and programmed. The Writer is able to write any custom text up to 40 letters long, spread over four lines.

False Sunrise

What you're looking at above is not a real sunrise, but rather a dawn sundog, which refers to particular kind of ice crystal halo. This atmospheric optical phenomenon is associated with the reflection or refraction of sunlight by small ice crystals making up cirrus or cirrostratus clouds in the very particular case when the sun is still below the horizon. The spread light of a false sunrise has less power than that of a real sun, but sometimes is amazingly similar in its visual behavior at distance. It is similar to a subsun, except that in a false sunrise the sun is below the horizon and the ice crystals are above it. Continue reading for more.

W House

The HouseW in Duiven, The Netherlands, seamlessly blends old architecture with modern style. According to the architects (Studio Prototype), the facade consists of "diagonal directions and is translated to a timber cladding of western red cedar battens. They are as slender as possible, creating tension with the heavy brick of the existing dwelling. Aluminum profiles are used to attain subtle transitions between materials and spaces. The diagonal pattern is opened up on several strategic positions, working as a privacy screen." Continue reading for more.

Giant Oarfish

Oarfish are large, greatly elongated, pelagic lampriform fish belonging to the small family Regalecidae. They are found in all temperate to tropical oceans yet rarely seen. The occasional beachings of oarfish after storms, and their habit of lingering at the surface when sick or dying, make oarfish a probable source of many sea serpent tales like "The Serpent of Gloucester" and so forth. The tales that have come from these odd creatures have struck fear into the hearts of many people before they knew what it was. Although the larger species are considered game fish and are fished commercially to a minor extent, oarfish are rarely caught alive; their flesh is not well regarded due to its gelatinous consistency.
