Tessy (short for tesselation) is an exploratory model displaying
complexity from one module that differs only in the way its folded up.
Basically the perimeter line of each module is exactly the same but can
assume a 30, 15, 0, -15, and -30 degree fold depending on its scored
condition. The design walks a fine line between material efficiency and
aesthetic complexity and ultimately achieves both by sacrificing double
curvature.
