If you enjoythis application, please consider buying the paid version. The paidversion has many more display possibilities: Brass Gears Clock LWP Paid.This live wallpaper simulates a pendulum clock. A pendulum clockkeeps time using a weight (not shown), gears, and pendulum. Thependulum is 38 and 1/8 inches (994 mm) long from pivot to pendulumweight center. Any pendulum of this length, even one you make athome, will keep very good second by second time.The clock is comprised of 13 separate "gears": 7 wheels, 4 sets ofpins, and 2 pinions. The initial impetus driving the clock tomotion is gravity acting on a weight, not shown, attached to a cordwrapped counter-clockwise around the shaft connecting the greatwheel to the great wheel's pinion (just above the 6 o'clockposition). The great wheel's pinion then imparts a clockwise forceon the hour wheel, while the great wheel imparts a clockwise forceon the minute wheel's pinion which is attached to and beneath theminute wheel. The minute wheel's teeth mesh with the pins on thethird wheel driving the third wheel counter-clockwise. The thirdwheel's teeth mesh with the pins on the fourth wheel driving thefourth wheel clockwise. The fourth wheel's teeth mesh with the pinson the fifth wheel driving the fifth wheel counter-clockwise. Thefifth wheel's teeth mesh with the pins on the escape wheel drivingthe escape wheel clockwise. The escape wheel is the end of the geartrain.The speed at which the escape wheel turns is limited by the twopallet faces of the pallets attached to the pendulum. The palletsalternately catch and release the escape wheel once per second. Inthis way, the pendulum regulates the speed of movement of all thegears of the clock. If all goes well, the escape wheel will turn360 degrees once every minute, the minute wheel will turn 360degrees once every hour, and the hour wheel will turn 360 degreesonce every twelve hours.The hour and minute hand are attached to the hour and minute wheelrespectively. The clock dial features hour and minute markings sothat an observer can tell the current hour of day from the hourhand, and the current minute of the hour from the minute hand.Attributions:This clock is inspired by Clayton Boyer's wooden clock designs,www.lisaboyer.comThe escapement (escape wheel and pallets) is of Clayton Boyers'sdesign, used here with permissionAll other "gears" (wheels, pinions, and pins) created usingMatthias Wandel's Gear Template Generator,www.woodgears.ca/gear/index.htmlHour and minute markings are based on a free clock face at TheWoodshop, www.thewoodshop.20m.com/clockfaces.htm (I havesubstituted my own roman numeral hours and chose to preserve IIIIrather than IV for reasons of symmetry)All images manipulated using the GNU Image Manipulation Program,www.gimp.orgAll images further compressed in size using the *awesome* Tiny PNGservice, www.tinypng.comClock display and logic written using the Moai cross-platform SDK,www.getmoai.comSciLua Time library used for local time calculations,www.scilua.org/time.html

Solar 2D Live Wallpaper is an interactive andscientifically accurate Android Live Wallpaper designed for tabletsand high resolution phones.If you just want to test drive Solar 2D Live, the free version ishere: Solar 2D LWP FreeUnlike other space-themed wallpapers, Solar 2D LWP is not"eye-candy". Instead it uses 2D images of the planets and Sun tosimulate relative position, speed, and size of orbital bodies.Although 2D images are used, the underlying mathematics computepositions in all three dimensions. You can see, for instance,Mercury rising above and falling below Earth's orbit (the ecliptic)from the edge-on view.You can interact with this background by touching individualplanets to set a focus, touching the Sun to unset a focus, touchingand sliding up or down to cycle through views, and touching andsliding right or left to rotate views.Features include:Scientifically accurate elliptical eccentricities (Kepler'sfirst law), points of aphelion and perihelion, inclinationsrelative to the ecliptic, longitudes of ascending node, variableorbital speeds (Kepler's second law), and orbital periods (Kepler'sthird law). All planets (including the Moon, but not the Sun) havecorrect sizes relative to other planets. All orbits (except theMoon) have correct sizes relative to other orbits. All orbitalperiods are correct relative to the selected orbital period ofEarth.Scientifically accurate stars, northern constellations, southernconstellations, and ecliptic (zodiac) constellations.Touch any planet to "fix" its relative angle to the Sun. Once aplanet is "fixed", the rest of the solar system and the surroundingstars will automatically rotate to keep it fixed. Touch the Sun toun-set any fixed planets.Touch and slide right or left to rotate the view.Touch and slide up or down to switch between views:top down view (slide up) edge on view (slide up) bottom upviewbottom up view (slide down) edge on view (slide down) top downviewView the inner solar system from top down, edge on, or bottom up.The southern constellations are visible from the top down view. Theecliptic (zodiac) constellations are visible from the "edge on"view. The northern constellations are visible from the bottom upview.ATTRIBUTIONS- This wallpaper was created with the Moai mobile developmentframework http://getmoai.com- Earth, Moon, and Venus art by Hansjörg Malthaner, http://opengameart.org/users/varkalandar- Mercury art by Shaber, http://opengameart.org/users/shaber- Sun art by Rawdanitsu, http://opengameart.org/users/rawdanitsu- Mars art by ???, http://opengameart.org- Star images generated with Stellarium http://stellarium.org- Hand drawn constellation diagrams based on Stellariumdiagrams
