Type any character and this demo splits its 8-bit binary code across a matching grid of 8 pixels, one bit nudged into each pixel’s color value. Click a pixel and the inspector shows the exact swap — RGB(123, 56, 200) becomes RGB(120, 56, 200) to store a “0,” a change too small to see. It’s a fixed teaching example, not a working image encoder, but it makes an abstract idea, steganography, completely legible on one page.
