wow that is so gorgeous! love the design and your "twisted" setup with crossing switch/accelerator is really cool and even if it's unconventional, you made the path looks pretty clear!
yeah, I'm also glad that I got the idea that if a particle direction is mostly perpendicular to a pipe, they don't interact, so I didn't need to put a "bridge" type of pipe to cross an existing path, like you often get in games like that
