These egg shells were cut with a high intensity precision laser beam. This gives a very good idea of what can be achieved with such an instrument. This is what laser surgery performed on one's eye is all about. Is it any wonder how one's vision can be improved in just a few moments? Science is sometimes wonderful, and it's still on the frontier of gaining new knowledge. Incredible what can be done with an eggshell and a laser beam.
Still, while the laser is a cool tool, it does take some artistry to create these. See for yourself.
