If you haven't heard of Reso in the last week, now is the time for a click. Literally.

You know circuit simulators like LogiSim and Digital, and you're looking for something different? Lynn Pepin has just that, and he has implemented a completely different approach to digital circuit simulations with Reso.

The thing a circuit simulator whose inputs are bitmap images. The outputs in are also bitmaps. And since these in turn can act as input again, it is possible to realize quite complex circuits with the help of composition.

The project has no UI and seems a bit weird at first. But once you get to grips with the concept, you'll soon start spending your evenings in a different way. It will be interesting to see, where the journey for Reso will lead. 

Cool project!
