Bauklotz Font :: Daryl Roske

Daryl Roske says this idea came to him when he and his daughter were playing with building blocks ("bauklotz" in German).  Instead of animals or little houses, they started creating letters.  Eventually, they created every single one and documented them in photos.  A simple idea, beautifully executed!

Looks like you can take advantage of an afternoon of playtime and license the font; just Daryl .
