Jasper (5 years old) and I were waiting for a BART train downtown at the end of an epic all day adventure. As we waited, we heard the sound of the muni trains arriving overhead.

Jasper said, “I think it’s a J.”

I said, “I think its a N.”

Jasper waited a few beats, and said “Nope, its a K” with full confidence despite complete ignorance.

I thought to myself “Wow. There’s a great game for a five-year-old”

A couple hundred hours later, I finished building 1.0 of that game.

I ended up building it using the ionic framework, and have published the android version of it on Google play. If you have 60MB to spare on your phone (due to lots of tiny videos of Jasper) and a small child who likes to guess things and touch screens, you should totally install it. I even wrote a theme song for the app.

“Nope!” uses realtime data from 511.org. If there is no internet, it just makes it up like Jasper would.

I also made the source code available. That’s just how I roll.
