Magpie Modular repanel for Non Linear Circuits - Let's Splosh
Let's Splosh is, hands-down, one of my all time favorite modules. 4 inputs gives you an instant 16 different combinations of difference rectified outputs. It can create a very interesting self similar recursive mess quite quickly especially when run in a feedback loop with other NLC modules. The build is remarkably straight forward too. Don't sleep on this one.
