I've thought about fabricating the terminal roof as the main feature of the building; manipulating the users' experience in the space as well as incorporating natural lighting into the building.
From Experiment 01, I decided to further develop the analysis of psychological tension on a surface (Experiment 01 was on a 'line'). A series of sine curves along y-axis generate an evenly distributed undulating surface.
Model 01. First attempt to generate the surface using sine curve and cosine curve alternatively along y-axis to create amplitudes.

Model 02. Definition allowing for sine curve amplitude to be adjusted via 'number slider'.

Model 03. Curvature analysis pattern on Sine-curve surface. From model 2, curvature analysis pattern was inserted to create series of circular holes along the surface. [in thoughts: Allowing natural lighting to penetrate through circular holes.]
[Added 'curvature analysis definition'] The series of circles gradually increase in size as the surface it situated on increase in degree of curve.
However, I was not able to maintained those series of circles as I started extruding the surface. [Need Help!]
Another alternative was to add a boolean definition for the circles to cut through the surface. Unfortunately with this definition, circles generated by the curvature analysis definition [because they overlapped] do not allow for boolean to work. Hence, long story short, I had to split those circles so that it won't overlapped and the surface ended up looking like a swiss cheese!! [still need to work on it].
