Marcelyn Gow reviews dozens of thesis projects produced by SCI-Arc graduate students 2006-2013, stressing the significance of minute nuances of line: frayed, tangled, calligraphic, fuzzy, sharp. She also discusses projects in terms of lines defined by folds, flips, stacks, trajectories, and tomographs. She concludes by classifying recent SCI-Arc thesis projects into fourteen categories inspired by ”The Analytical Language of John Wilkins” of Jorge Luis Borges.
