Your own photos, videos, songs, and files, turned into splats on your device. Nothing is uploaded.

Make and convert

  1. 3D PhotoA depth model guesses relative depth from one photo, not distances in meters.
  2. 3D VideoA video is a string of photos, and a computer can guess how far away each part of a photo is.
  3. 3D WorldA video is a string of photos from a moving camera.
  4. Model to SplatsA 3D model is usually a mesh: a net of flat triangles with colors or a picture (a texture) painted on them.
  5. Song LandscapeA song is a wave, but you can also see what it is made of.

Open your own files

  1. Photo AlbumA photo album keeps printed photos on thick pages.
  2. Picture FrameA picture frame protects a photo and sets it apart from the wall.
  3. 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.
  4. Splash BookA book is a stack of pages bound along one edge, so you can turn them one at a time.
  5. MoleculeA molecule is a group of atoms held together by chemical bonds.
  6. Thermal EllipsoidsCrystallography describes an atom's average position and spread with a displacement tensor.

Scan and measure

  1. 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.
  2. Electron MicroscopeA scanning electron microscope sweeps a fine beam of electrons across a sample in a vacuum.
  3. Fruit MRIAn MRI scanner (magnetic resonance imaging) uses no X-rays.
  4. 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.
  5. 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.
  6. Room Echo MeterReverberation is sound that keeps bouncing around a room after its source stops.
  7. Super-Res MicroscopeOrdinary light microscopy struggles to separate nearby objects about 200 to 300 nanometers apart.
  8. Thermal CameraEverything gives off infrared light, more the warmer it is.

QR codes

  1. QR CodeA QR code stores text in a square grid of dark and light modules.
  2. QR ExplainedA QR code is a grid of dark and light modules with a fixed plan.
  3. 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.
  4. Triple QROne square holds three QR codes here: the first sets each module's red, the second its green and the third its blue.
  5. Picture QRA QR reader samples the center of each module.
  6. Video QRA QR reader only looks at the middle of each square.

Sound and light

  1. Sound in a BoxSand on a ringing plate gathers on the lines that stay still.
  2. Chladni PlateIn 1787 Ernst Chladni sprinkled sand on a metal plate and drew a violin bow along its edge.
  3. 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.
  4. Splat MirrorTap “Start camera” and each splat takes the color of its place in the picture, so the mirror shows you, live.
