Logic is an alternative to wiremod that is designed to be faster, more flexible, and easier to use.
It is powered by a powerful server-side back end which is supported by a clean client side GUI, drawing inspiration from the blender nodes editor and lego mindstorms. Users design circuits with the editor on the client, then send them to the server to become part of the system. Errors cause the latest update to be reverted server side, and error messages are sent back to the client for debugging.
Advanced features on the distant, but not too distant future list include a wiremod compatibility layer and client side code evaluation with debugging.
