Ever heard of phyllotactic spirals ? John Edmark was inspired by these naturally occurring leaf patterns to create a series of sculptures he called “Blooms”.
This is the starting point for our project, Phyllo.
As John Edmark explains in this instructable, he spins a Bloom under a stroboscopic light to create the illusion of a flower blooming.
In our project, we will build upon this and:
- Color each petal individually from the inside with stroboscopic LEDs.
- Play colorful animated patterns on the sculpture (such as falling or rising petals, lines, spirals, rings…).
- Display animation patterns across neighbouring phyllos: when two sculptures are close enough, they can synchronize and the animations will propagate from one to the other, creating globally coherent phyllotactic patterns.
Here’s a simple 3D simulation as a basic example of a revolving spiral:
