Besides being a lot of fun, the Rokenbok Airport video is a great demonstration of Play Level 2, Preschool Remote Control. It shows how ROK Blocks and Rokenbok construction work together, both in the construction of one of the terminal buildings and the tow-able jumbo jets. There is also a wonderful example of Level 4 Advanced Play; a massive airplane hanger with a rolling door operated by the X2 Dual Drive Power Unit.
