"GramCube" is a patented device for creating sentences in English in Present Simple, Past Simple, Future Simple, Imperative and sentences with modals. Just turning the cubes you get 200+ sentences in English. When translating from your language the number can be bigger. For example, it can translate 364 sentences from Russian into Engish. The patent in Russia belongs to me (PeterStepichev) and I offer it first-hand.
