I really like @Stephen Paul Weber's https://www.crowdsupply.com/singpolyma/big-buck-bunny-board-book : extremely humble short-term, but in pursuit of a non-humble long-term goal...a free culture.

Read recent update "Creative Freedom for Children Who Become Adults" https://www.crowdsupply.com/singpolyma/big-buck-bunny-board-book/updates/1815 and buy hardcopies for children you know.

Go back him already https://www.crowdsupply.com/singpolyma/big-buck-bunny-board-book !!! :)
