This cube brings a unique characteristic to solving a Rubik's cube that no other cube does... the ability to say "I solved it without even looking at it once."
Rather than building hand-eye coordination, it builds hand-mind coordination.
I find that solving this cube is a challenge above and beyond a normal rubik's cube. It takes me significantly longer to solve than a normal cube. But as a result my speedcubing times on regular cubes have dropped exponentially. Because it uses areas of my brain a normal cube do not (memory/perspective... seeing it in touch and shapes rather than eyesight and color).
It is also a bit heavier than a normal rubik's cube... helping me build muscle/speed for my speedcubing (speedcube is where you try to solve it as fast as possible.)
Step 1: What you need
-A Rubiks's Cube (authentic or fake)
-54 Uniquely Shaped Metal or Plastic Tabs (more on this in how-to)
-A Razor Blade of your choice (careful!)
-2 Part Epoxy for use with plastic/metals
-Toothpicks or like for mixing/applying epoxy
