Here's my Ivan wormhole design. Pretty cool to look at, but it really lags my game. It makes a lot of money, too.


I wasn't feeling too great about progressing, so I decided to build a highly useless but IMO pretty cool production area sort of thing. It's got a storage area and disposal system for things that can't be used in the single input machine.
One thing I immediately see in this design is that you could get things like glass in the storage area for the single input. So I could put more single inputs in a chain for the two input machine. Ouch, this is hard to explain. But it makes pretty cool usage of the 3D printing & scanning buildings.

I'll post more stuff here as I make it. Thanks for reading, feel free to give ideas and improvements in the replies... I feel like this game has some pretty cool potential in it's building aspect.
