Ideas for art style

I've been trying to work out what Jack should look like. Here is one idea:

A blueprint has the joint benefits of being simple to draw, and somewhat unique. I still don't know what the best way to implement switches etc would be. I could always do it as a blue print now, and make it more 16-bit pixelly later.

This is only an idea, which may or may not end up being implemented like this. But it honestly is an idea I like.
