A Steno Learning Card Game

Last year around this time, I blogged about a word game my kid got for his birthday that I thought I might be able to turn into a steno learning game. I'm afraid I never got very far with that. The kid has learned a little bit of steno since then, but not a huge amount. There's a card game called Stenophonatic, made by the people behind Dictionary Jumpstart, a venerable but rather expensive proprietary dictionary-building app (with a pay-per-word-list business model). I really like the idea of a steno learning card game, and I have to admit I'm a little bit tempted to get it, but I'm on the fence, primarily because it's $35. My realtime-all-the-time steno sensibilities sometimes conflict with my parental instincts to make stuff offline and analog for my kid whenever possible. He does have an Android tablet (that I keep meaning to install Dotterel on; haven't gotten around to it yet), but I often think it's helpful to make pedagogical tools physical and concrete. Anyone have any ideas about ways to bring steno off the screen? If I do wind up getting that card game to play with my kid, I'll certainly let y'all know how it goes.
