3D- Maquette Plans

Using this basic model of the tessellating shapes from Escher's work, I have developed the idea into creating a rearrangable cityscape. While I could take this further and create a bigger piece, I wish to somehow apply the detail of my current technique (etching onto the blocks perhaps).

Could also use the blocks, rearrangable as they are, as a source for layouts of future sketches, before setting them as I want and apply details?
