All right. This one I have been agonizing over for quite a while now and I REALLY want to know what it is.
What I remember is that the base of the game is that you have a workspace where you drag all sorts of gadgets onto the space and connect them with these wires. The "campaign" part of the game had all sorts of different puzzles where you needed to add gadgets or change something so that the ending gadget went off when the right input went down the wire. But the important part was the sandbox mode where you just put down what you wanted.
The different gadgets included some normal things like a pendulum, calculator, counter, timer, some weird things like a variable g chamber to drop things down, a cannon shot simulator, sound creators. And the important parts were some Boolean gates and switches (I remember the switches looked like actual railroad switches). There were also decals to decorate things with.
I really want to find this game again, because I just started a computer science class, and when we were talking about Boolean gates, I realized I already knew this stuff, from this game. And now that we are creating logical circuits, I want to simulate them in this program, because our example software is horrible. I remember in this game the connecting wires would follow the gadgets around as you dragged them, and you could create fixed points in the wires.
Please help.
