PROJECT DELTA

                                   A new way of designing  and making  of the Platonic and Archimedean Solids,                                                             by considering  the solids as sets of pyramids with their apexes gathered at their centres.

                    We are pleased to be working with Tarquin Publishing to bring these products to market.                                                        Tarquin is a well-established publisher and distributor with a specialism in mathematics.

                 See their website for their range of  hundreds of books, posters, dice, educational toys and games

All living beings belong to the same large family, so we shouldn't be too surprised to see other species enjoying geometry. How many radii does the shape which the puffer fish makes have?
