Kre-O Kre-O KRE-O is a line of construction toys (similar to Lego and Mega Bloks) manufactured by South Korea-based Oxford and marketed by Hasbro. Kre-O was released in stores in Fall 2011. The name "Kre-O" comes from the Latin word "creo", which means "I create". Kre-O toys feature highly articulated humanoid figures called Kreons. Kre-O blocks are compatible with Lego bricks, hence also compatible with Mega Bloks and other building block brands. Kre-O "Transformers" is the first line of the Kre-O series. They were first shown in February 2011 at the American International Toy Fair trade show in New York. Transformers
Zome green strut cannot be placed directly adjacent to a red strut or another green strut with which it shares the same hole (even though they are mathematically distinct). The Zome system is especially good at modeling 1-dimensional skeleta of highly symmetric objects in 3- and 4-dimensional Euclidean space. The most prominent among these are the five Platonic solids, and the 4-dimensional polytopes related to the 120-cell and the 600-cell. However, the list of mathematical objects which are amenable to Zome is long, and an exhaustive list is not forthcoming. Besides those already mentioned, one may use Zome to model the
