I stumbled upon a marvelous new plugin and I never hear about it so I thought I would give it a little PR. It is called NetCreator and it connects with splines all kinds of objects. I used it initially for creating neural networks simulations between clones (neurons) but it also works for Thinking Particles and polygonal objects among others. It is free and incredibly useful.
It probably does some of the duties of X-particles but I don’t have that.
