I don't know what else to say except this glitch is weird. And there are is no shortage of interactions between them!
I can also say this is only one possible configuration. I have not dared to see what happens if paths are longer, multiple paths of the same direction are crossed (although, non-crossed they don't seem to do anything), etc. So feel free to experiment on your own.
Nonetheless, I strongly advise that anyone playing this be prepared to enter a realm of true wonder / horror. I myself am too afraid to test all possible combinations myself. I highly recommend that, if anyone were to try to make a level out of some combination of these, that they make it as clear as possible what the player is supposed to do; otherwise, it's nothing short of a beyond-preposterous guessing game.

Have fun, and please feel free to share your findings here. I may test this myself one day... but the number of combinations is truly frightening. (And, again, this is for one configuration, although I think it's probably the most interesting one.)
