I'm working on a neo-retro modern-80s style virtual home computer! It's called Mini Micro, and it uses MiniScript as both the command language and the programming language. In addition to the standard MiniScript intrinsics, it'll have an API as defined here that lets you easily make 2D games. This Flappy Bat game took less than an hour, and that was while monkeying with the underlying code (adding non-uniform sprite scaling, for example) too. I'm super excited about this project — I think it's going to be a fantastic way for newbies to learn programming, and for old timers to hack around and have some fun too.
