Expanding Duodyadic Tiles

Heh. "This reminds me of a circuit-building kid I had in elementary school" ... "I'm pretty sure I know what you're talking about and I have one in my basement right now."

Duodyadic tiles challenge: codegolf.stackexchange.com/questions/48009/…

This is a chatroom to discuss modifying my idea of duodyadic tiles into something that is a full fledged programming language. I'd probably write an interpreter myself since it may be too tedious for a golfing challenge. Here I'm looking for input on what people think the different types of tiles should be.

Premise:
Instead of having 2 inputs and 2 outputs, each side of a tile could be an input or an output (which means data could flow in any direction). Each output is a separate function of all the inputs (so it's no longer "doudyadic").
