Typing on phones is a drag. Programming requires typing. Game over for programming on touch screens, right? What if programming didn't require typing? Here's a first shot, very incomplete.
Still too early to call this programming. If you squint and turn your head to the side you can see something like a function with no parameters. There are no loops, branches, nor variables. But it does work on a touch device.
