I started by trying to make a perpetual ball machine, but in the end I made lift/element hybrids. Eventually I made a ball machine where network 2 did not have any motors. Here's a guide to more of these!
If you have designed any lift/element hybrids, contact me and I'll add them!
When no balls are on this hybrid, it has a particular orientation. When balls are added in the designated areas, this flips over raising one ball but the other is lowered even more. To make your own, copy the pictures. Note that the majority of it is double-layered.
