Binary Logic Simulator
The game has a simple interface and the premise is that you are guided through learning how different logic gates work, and how they are fundamentally created from other "universal" gates. Starting from just simple NOT gates, all the way to more complicated logic systems such as a binary clock. Then, once you have learned all the basics, you can create your own circuits in a sandbox mode.
The nucleation point of this project was that a co-worker of mine that is fascinated with technology and what it can do, was asking all sorts of questions about IT and programming and they were genuinely interested in computing as it seemed so foreign to them. So, I created it as a learning tool for them and a visual aid to show what I was saying in action.
