Reviews

'The author has produced a reference work for those wishing to construct regular polyhedra and an interesting collection of photographs of plants.' -- Science Group of the Anthroposophical Society in Great Britain Newsletter 'Simply an excellent guide book ... it subtly leads into a meditative state followed by the catharsis of achieving perfection. Beyond that it encourages the intelligent eye to go exploring for these shapes in nature ... a splendid inspiration.' -- Francis Cameron, Pentacle Magazine 'A simple and beautiful book ... The beauty of the proportions is palpable, especially when illustrated alongside the flowers whose designs reflect the same principles. The instructions and illustrations are equally clear.' -- Scientific and Medical Network Review, Winter 2007
