Factorissimo but instead of a factory warehouse it's a copy-paste circuit warehouse.

A composite combinator combined with combinations of combinators from a combinator combinator. Allows you to "enter" a special combinator to build a circuit network inside it, which is then deployed over this special combinator in the real world. This lets you seamlessly condense complex circuitry and signals into a single combinator. Blueprint Compatible.

This mod is perfectly efficient and optimized on performance because it literally uses tiny combinators, and the surface it creates when you enter it is only temporary while you build or edit them.

Chips are particularly useful for creating copies of circuits that are frequently used, as well as sharing circuits that you may need to make changes to.
The blueprinting and copy-paste features make it very simple to update your chips.
Building and editing is as simple as throwing the wrench-like entry/exit tool at it.
It is done this way to prevent ambiguity as to which combinator you're trying to enter when there are several nearby, as well as no randomly being teleported to the circuit surface unless you're specifically looking to edit it.

Note: Lua-driven combinators may not work inside these circuitissimo chips, but those mods will work just fine placed outside.
