As for my guesss at what it is, here goes:
Calculating the reverse vector of a simulater-driven CNC requires more than the measly pictures that have been provided to us by the Root Administrator of both this site and this thread (that is to say, Adam). But, if I were pressed to establish my own hypothesis, I would hazard that it is a construct designed for the purpose of delaying the realisation of the readers/viewers in regards to what the purpose of the device is, in order to satisfy the site Moderators desire to frustrate the viewers/readers.
In other words, I think its a device made to stop us figuring out what it is, due to the mods strange desire to annoy us.
