Six months after our first working session, we have a live prototype. In early August, we typed *120*1994# into a phone and ... got the screenshot below. We then fleshed out the menus, put in some logic to connect users and groups, and hooked it up to send out SMSs. We're now pausing to do a rewrite of the foundation of the code, as well as connect up a simple web application.
If you're in South Africa, you can play with it right now. Just type *120*1994#. You'll get more than one "we're working on it" message, and it needs ... a lot of work. From now on, we'll be improving it every week, though for a little while that will continue to mean the plumbing more than the decor. We'll do another update when the web application goes live.
