When we launched the v1012 update for SpaceChem two months ago we announced a challenge to create crazy designs using the new sandbox mode. It is now time to announce the winners!
Recycler, by GuavaMoment
Ever wondered how SpaceChem’s recyclers work? So did GuavaMoment, who submitted this design for a recycler that accepts any kind of molecule and breaks it down into a stream of hydrogens.
Cellular Automaton, by R. Daneel Olivaw
It might be best to let him explain:
It is an implementation of a cellular automaton using a molecular ring. Technically, it is a one-dimensional elementary cellular automaton of length 12 with periodic boundary conditions. Using a common template and toolbox, there are actually several sandboxes that implement a variety of the Wolfram rules for cellular automaton.
Tic-Tac-Toe, by cake>pie
ResearchNet regular cake>pie decided to take the meta route and recreate tic-tac-toe in SpaceChem. Moves are specified by using pairs of H/He/Li to describe coordinate positions. The design includes error checking to ignore illegal moves and support for both player specified moves and random moves (as shown in the video).
Brainfuck Interpreter, by Peer
The only reason SpaceChem’s sandbox mode exists is because of an email I received from Peer, who was working on building a computer in SpaceChem but needed more power. With the release of sandbox mode he was able to follow through and create a programmable interpreter for the brainfuck programming language.
The following video demonstrates a program that inputs two numbers (4-bit integers), adds them together, and displays the result. You can click the links at the beginning of the video to learn about the individual subsystems, and can click the link to the video itself to learn more about the project and instruction set.
Thanks to everyone who entered!
