Well, this escalated quickly. Trying to get more interesting worldspace-based effects happening (basically, a ripple would be nice) but until then, these unforeseen behemoths sure are interesting. The hotshot line is: ico.geometry.vertices[i] += Math.sin(clock.getElapsedTime() * ico.geometry.vertices[i]) / 2; (for all axes individually) [everyday 5/28/17]
