This effect originally called Bloxo, was invented by John Rice and sold by Harry Stanley c. 1960.
Pagoda is the definitive version of the the effect using a solid blade or rod to secure the blocks and was created magnificently by the Dutch master craftsman: Eddy Taytelbaum. Eddy did such an amazing job he inspired many craftsmen including: Alan Warner, Mel Babock, Milson-Worth and more recently Magic Wagon to create their own versions.
However, one feature that Marvillo invented is the ability to let the chosen blocks release one at a time as chosen by the spectator. This might be possible with some of the other versions once you know what to do but not with most, and Marvillo specifically designed his box to permit it. This box is a little chunky when compared to the fine lines of Eddy Taytelbaum and Alan Warner, but still looks good and works very well.
