• Ned Batchelder: Spore creature creator and steganography
  Looking at the PNGs on the Spore page though, they have not done this. There is no data other than the image. But dragging the PNG into Creator does indeed give you the creature as structured data. Renaming the PNG doesn't affect the data transfer, but any sort of editing of the image does. They're using steganography, hiding one message inside another. In this case, they seem to be using the least significant bits in all the pixels.
