Mission:
Create application that makes ASCII art from pictures.
How does it work:
Press "Convert" button, open your image, save your HTML file. Default width symbols are 200 and it is optimal symbol count for quality. You can choose different width symbol count yourself.
It's taking every your image, makes it black and white. Then it applies symbols from black to white.
