Splashes that make something from what you bring, or measure what they show.

3D PhotoA depth model guesses relative depth from one photo, not distances in meters.
Playground
3D VideoA video is a string of photos, and a computer can guess how far away each part of a photo is.
Playground
3D WorldA video is a string of photos from a moving camera.
Playground
Model to SplatsA 3D model is usually a mesh: a net of flat triangles with colors or a picture (a texture) painted on them.
Playground
Song LandscapeA song is a wave, but you can also see what it is made of.

Photo AlbumA photo album keeps printed photos on thick pages.
Playground
Picture FrameA picture frame protects a photo and sets it apart from the wall.
Playground
Picture LabThe Picture lab shows a page, a photo, a GIF or a video as Gaussian splats: thousands of small, flat, colored discs, the same stuff every splash here is made of.
Playground
Splash BookA book is a stack of pages bound along one edge, so you can turn them one at a time.
Playground
MoleculeA molecule is a group of atoms held together by chemical bonds.
Playground
Thermal EllipsoidsCrystallography describes an atom's average position and spread with a displacement tensor.

Scan and measure
Airport X-rayAn airport scanner sends a fan of X-rays through each bag as the belt carries it past, and a row of detectors measures what gets through, one line at a time.
Playground
Electron MicroscopeA scanning electron microscope sweeps a fine beam of electrons across a sample in a vacuum.
Playground
Fruit MRIAn MRI scanner (magnetic resonance imaging) uses no X-rays.
Playground
CT ExplainedA CT scanner (computed tomography) turns an X-ray tube and a curved row of detectors around the object, taking hundreds of views from every side.
Playground
Walnut CTThis is a real walnut, scanned with X-ray CT at CWI in Amsterdam: more than a thousand X-ray pictures taken from all around it, worked back into a volume of how dense the walnut is at every point.
Playground
Room Echo MeterReverberation is sound that keeps bouncing around a room after its source stops.
Playground
Super-Res MicroscopeOrdinary light microscopy struggles to separate nearby objects about 200 to 300 nanometers apart.
Playground
Thermal CameraEverything gives off infrared light, more the warmer it is.
Playground
QR codes
A QR code stores text in a square grid of dark and light modules.
Playground
QR ExplainedA QR code is a grid of dark and light modules with a fixed plan.
Playground
QR Damage LabQR codes still scan when part of them is lost, because error correction can rebuild missing codewords: about 7, 15, 25 or 30 percent at levels L, M, Q and H.
Playground
Triple QROne square holds three QR codes here: the first sets each module's red, the second its green and the third its blue.
Playground
Picture QRA QR reader samples the center of each module.
Playground
A QR reader only looks at the middle of each square.
Playground
Sound and light
Sound in a BoxSand on a ringing plate gathers on the lines that stay still.
Playground
In 1787 Ernst Chladni sprinkled sand on a metal plate and drew a violin bow along its edge.
Playground
ScreenA screen made of splats shows a video or a GIF: every pixel of the picture is a small splat whose color changes with each frame.
Playground
Splat MirrorTap “Start camera” and each splat takes the color of its place in the picture, so the mirror shows you, live.
Playground
In every Splash
Every Splash takes the same effects: Poke, Wind, Dissolve, Twist, Slice, Drop, Magnet, Paint, Move, and Clay. They are in the Playground's Effects sheet, each with its own settings.
Views show how splats work: Cutaway, Show the splats, Heat map, and Scrub and slow motion.
Make and share
Save a picture, a turntable video, a GIF, or a PDF that carries the Splash's credits. Record up to a minute with sound. Copy a link that keeps the view, the effects, and the splat count. Share and embed has every option.
