Typocartographer allows you to draw text with typographical parameters that change continuously along each sentence.
For example, your sentence could start with heavy letters that have marked serifs and end with ultra light letters that are sans-serif.
Change the size, thickness, width, slant, serifs, contrast, junctions and x-height of the letters as they move through the page in straight or curved lines.
Then, export it all to an SVG document for download!
Typocartographer is an effort of the University of Victoria and the University of St Andrews. It is free to use. Contact us if you like it, or if you don't at infotypography@gmail.com
