Some research on playful typography coded in java under processing.
A shape placement sketch from an svg file on glyphs (PARTY).
Another that grows 3D splines on glyphs (Soen).
A sketch (2D) of sheets (based on Bézier curves) added to the edges of the glyphs respecting the tangents (TYPOGRAPHY). There is an animation that matches here.
And a small video on "flocks" and glyphs here
