This site takes images like this:
And turns them into ASCII art, that is, pictures made from standard keyboard characters. As wikipedia explains it:
ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII)… ASCII art can be created with any text editor, and is often used with free-form languages.
Here’s a screenshot of the converted image:
And a closeup. It’s a bunch of tiny “#” signs in different colors.

Don’t think this service has a practical application, but it’s cool. Check it out, it’s called PICASCII.
