This toy prototype helps your kids not only their ABCs but also the basics of font design. Instead of 26 distinct letters, the oversize, 4-inch recycled-cardboard cubes (known as “Letterboxes”) divvy up the alphabet into combining geometric parts. The cubes can be stacked in all sorts of combinations to produce a variety of shapes and letterforms. The typeface is available as a free download.
