Some geometric figures can be extremely beautiful to our eyes, due to their highly symmetry and homogeneity. Like islamic patterns and tilings, whose beauty is based on crystallographic group symmetries, the beauty of (semi) regular polytopes, is based on their symmetries which can be easily described by root systems. This discussion is illustrated with some string works done by students of maths at the University of Almería, and other string works done by the author. Among these, we show the Petrie projection of , which has a rotational symmetry of order 30, another projection of of order 6, suggested by Tom Ruen, and some string work based on tilings from the Alhambra of Granada, and the Alcazar of Seville.
