WebBecause the rotation is driven by rand(@ptnum), each point gets its own random rotation, meaning each circle gets its own random rotation. When this nest of circles is then passed to the 2nd copy sop, it just does what its told; finds each point, and copies a box onto it, using @N and @up to orient it.
