Erik D. Demaine, Martin L. Demaine, and Jason Ku over at MIT created an origami maze puzzle font, which is a template that shows you how to fold 3D letters of the entire alphabet.
(c) Crease Pattern of the Alphabet: Dark lines are mountain folds; light lines are valley folds; bold lines delineate letter boundaries and are not folds.
(c: Crease Pattern) folds into (b: 3D extrusion), which is an extrusion of (a: 2D maze)
Paper planes are so simple, yet it inspire admirers for different reasons. The act of folding paper planes and testing its aerodynamics is so satisfying and fun! Jamming to the paper planes song by MIA is pretty hip too. May I suggest, the stylish flying paper plane wall decals by Mel Lim from Blik? And lets not forget Dawn Ng’s art installation “I fly like paper get high like planes.”
