Calling all indie and open-source developers!

There is a severe lack of free or inexpensive and easily accessible educational games for our youngest children!  It's time we solved that and gave teachers a hand.  The purpose of this jam is to inspire small indie and open-source developers to see education as the severely underdeveloped market that it is.  I am looking for submissions such as: letter and number tracing practice, number/letter sound identification (be sure to check the most recent studies on phonics - you're probably saying the letters wrong!), shape identification, fine/small motor development, simple math skills (count and match the number), and so much more.  Bonus points if you use a font designed for early education and double bonus points if it's designed by an educator!  Submissions which include downloadable iOS and Android executables are preferred!
