18.104.22.168 Waterbomb / Flagstone Tessellation
The finished, folded design. A little rough around the edges but I think it demonstrates the basic premise.
I picked this design somewhat at random just to see how my waterbomb->flagstone process would work, and it came out pretty decently. This same technique can be applied to pretty much any 2D tessellation that can be folded with normal pleating methods.
