I love activity books. I always have. Activity books geared toward adult designers? Even more love.
"Hyperactivitypography from A to Z is an activity book for typographers illustrated in a nostalgic vintage style to give it a sweet and childlike look. The book is packed with activities, ranging from silly to hard core nerdiness. "
The books are currently sold out (and why wouldn't they be), but you can find out more here.
