I propose six new block types, all of them likely a compacted block.
The tech remnant block would be the circuit board design with no “edges” so the pattern flows together, like soil.
The tech Component block would be a mass of wires running one direction. Blocks stacked in the proper direction would be seamless, like brick.
The tech device block would be a repeating, red tech pattern kinda like machined copper.
I imagine a medium fossil block would be a stack of bones that also works like brick.
You get the idea. That would open whole new avenues of design.
