@meeper afaik there hasn't been a whole lot of proper testing done on them.

i came across them while reading about liquid state machines and spike net stuff doing very impressive and near-brain things, but i haven't tried to get them to compute things yet. just been curious because the way they are built seems like they might get around some issues with contextual memory (because splines) and they might do well at wide-but-shallow nets since the derivatives don't actually mix all over everything like they do in other layouts
