The hula-hoop has been enjoying a comeback for quite some time and now a London-based artist has developed a smartphone app to help improve technique. "Marawa The Amazing" provides tips and tricks in the app and demonstrates the best way to swing a hula-hoop. Marawa is an expert and on her homepage she claims to be able to keep over 100 hoops going at one time.
She also has a keen business sense and has an online "Hoopermarket" where she sells all kinds of hoops in different colours and sizes.
