Low-Poly-Model made with Cinema4D v. 9.6 using Hyper-NURBS. Aperture can be easily opened or closed by rotation of one segment that is marked in the c4d-file. It is also possible to set the time frame for changing aperture. Also the number of segments (and their pivots) can be increased by increasing the copy-parameter-number of the 'array'-object. Animated model, see animation.
