E-Learning for Toddlers and Pre-Schoolers: HTML5 Alphabet Learning/Hand-Writing

Next up in my little “E-Learning for Toddlers” series is this example which was extended/based (i.e. blatantly lifted) from the excellent “Stay-in-the-Letter” initial concept by Chris Heilmann which I saw on the Mozilla Hacks blog:
https://hacks.mozilla.org/2013/06/building-a-simple-paint-game-with-html5-canvas-and-vanilla-javascript/
My pilfering of this little app concept was for solely and completely personal reasons for teaching my own son, as I simply wanted to see if I could extend it to support the main Japanese characters (hiragana/katakana, maybe even kanji at a later date) as well as extending the English alphabet which it was already designed for to also provide phonetical readings of each character (should work whether using in English or Japanese mode).
BC$ = Behavior, Content, Money

The goal of the BC$ project is to raise awareness and make changes with respect to the three pillars of information freedom - Behavior (pursuit of interests and passions), Content (sharing/exchanging ideas in various formats), Money (fairness and accessibility) - bringing to light the fact that:
1. We regularly hand over our browser histories, search histories and daily online activities to companies that want our money, or, to benefit from our use of their services with lucrative ad deals or sales of personal information.
2. We create and/or consume interesting content on their services, but we aren't adequately rewarded for our creative efforts or loyalty.
3. We pay money to be connected online (and possibly also over mobile), yet we lose both time and money by allowing companies to market to us with unsolicited advertisements, irrelevant product offers and unfairly structured service pricing plans.
