Well after feeling slightly inspired by Minecraft and their redstone circuitry I decided to try a similar system in Graal. After a few hours of work I've finally decided to release my (loosely-based) implementation of circuits on Graal.
My main goal was to have a circuit system that automatically adapted based on it's surroundings, and have power transfer through start power source to it's end point.
The system is mainly event-based which means you can easily make your own power receivers (I.e: Power Activated Doors, Explosions, etc.).
My current power sources are activated by being grabbed (you will need an onActionGrab system) and the pulsing mode is activated by left-clicking an active power source.
Thanks to Trigger (from Classic iPhone) for the Wire and Repeater/Power Source graphics, and whoever made the ocarina sounds I found in Zodiac's sounds folder.

No look at it, Stefan is totally trolling Thor. Calling Classic a "playerworld" (something it's not supposed to be) is the ultimate subtle insult to a true fan.
