If you want to challenge the limits of your manual dexterity, spatial understanding and credit limit, then you need this cool new Superplexus Vortex. This $30,000 three-dimensional spherical labyrinth challenges you to manuever a wooden marble down 31' of track that contains a complex network of chicanes, multi-planar hairpin turns, spirals, staircases and even a vortex. This massive 3D maze is handmade from 3- and 6-ply Finnish birch over the course of 400 hours and set inside a 36" diameter acrylic sphere that is affixed to a Jatoba base using a stainless steel gimbaled mount that allows you to tilt the sphere in any direction to guide the marble. It takes a minimum of 425 precision turns of the sphere to get the marble from one end of the path to the other and a series of directional arrows are there to help point you in the right direction.
Although this luxurious brainteaser has way too steep of a price tag for most individuals out there, it would make a really functionally cool decoration in a corporate lobby, especially for banks that got bailed out. For the rest of us, there is a smaller, portable version called the Perplexus that is much more affordable and just as mind-bendingly fun.
