John always had fascination with aesthetics and symmetry of materials, which was in part inherited from his mentor Cyril Smith. This fascination was reflected not only in his beautiful equations, but also throughout his career learning about and predicting well-organized shapes, defects, and structures. John always had a kin interest in experiment and in interaction with experimentalists. Naturally, the aesthetics and underlying laws of the icosahedral phase discovered by his friend Danny Shechtman enchanted him; he got deeply involved in quasicrystal’s research for many years. My association with John was mainly related to quasicrystals: whenever I was lucky to discover by electron microscopy something new, John was always of great support. I am happy to present a few examples of my collaboration with John that are related to the celebrated icosahedral symmetry: (1) work on crystalline aggregates with icosahedral symmetry; (2) work on special grain boundaries based on local symmetries; and (3) work on highly ordered noncrystalline metallic phase coined by John the Q-phase.
