This image shows the contracted braille transcription of the phrase "Dotless BRAILLE" as simulated braille dots. The dot 6 cells used for the capital and double capital indicators are shown in a different color, green, because they don't have a direct print equivalent and also to match the image of the logo.
The image uses a client-side image map so if you point your mouse at any of the cells, the displayed ALT parameter is the dot pattern such as "Dot 6" for the first cell.
