Toys, Games and Hobby Products Design triX Modular Toy by Vladimir Zagorac triX is a connectable concept toy for children above the age of three which enables virtually unlimited exploration and expression in tridimensional form. Devised around a complex grid pattern, it can contribute to development of spatial thinking, while a small number of parts can encourage creativity. Parts with ambiguous symbols assist the child in expressing emotions and creating new and interesting characters, while getting a different connotation depending on rotation and placement. This encourages interaction between youngsters and can help develop social skills.
