From the developer:
LoCAD is an application for designing and simulating digital circuits. Special emphasis is given to simple creation and graphical visualization of a circuit's functioning. The inputs and outputs of the elements can be wired quite simply. In the simulation, you can watch the current flow and thus follow the cycle of state changes.
You may want to check out more software for Mac, such as Loca Studio, Grave Mania: Undead Fever or SourceCounter, which might be similar to LoCAD.
