These are a series of generative typographic illustrations done for Collins for the 35th Type Director's Club Annual. These were created by generating clouds of particles based on typographic forms, and subjecting them to varying turbulent forces. Others used scripts to create and deform wireframes. The result are living, animated typographic shapes, which counter the static idea of how a font or character should be represented. Out of dozens of generative shapes, only around ten were chosen as illustrations for the annual. See the animated video and static renders below.

Instead of spheres, lines were used as particles to generate the "T" below.
