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
Step 2: Obtain Rubik's Cube
Step 3: Obtain 54 Round or Raised Square Metal Tabs of 6 Different Raised Shape Designs
WARNING 1: The Designs must FEEL different from each other. Each shape needs to have a distinguishing characteristic to differentiate it by touch rather than sight. THIS IS IMPERATIVE.
WARNING 2: It is best to ensure that each of the 6 shapes is quadratically symetric* in design (i.e. turning the shape 90 degrees yeilds same design as before turned). This ensures that after mixing and solving... the cube looks complete (note that one of my shapes does not follow this rule).
Many who are new to Rubik's cubes are unaware of the fact that if you were to draw arrows on each square of the cube when you buy it, solving it to perfection is not as easy as some pieces will not be soundly placed (arrows in all same directions). See picture for understanding... you see the colors are all in place... but the cube is not truly solved. Unless you know how to solve a cube like this... you will want to ensure the designs on the tabs are symetric as I mentioned.

Step 4: Peel Stickers Off Cube
Step 5: Etch the Cube in Prep for Epoxy
Step 6: Etch Back of Metal Tabs/pieces
Step 7: Clean Cube and Tabs With Alcohol
WARNING: This will not harm an authentic Rubik's cube. If your cube is not authentic... it might be made from a form of Acrylic... if this is the case either SKIP THIS STEP, or use soap and water and let completly dry... as alcohol would melt/crack/damage your acrylic cube.
Step 8: Epoxy Pieces to Cube
NOTE: I would have used gorilla glue, but did not want to clamp these down (a necessary step requiring clamps I did not have). Also... Gorilla Glue (as awesome as it is, seriously that stuff HOLDS) expands 3 times and if not used carfully would look messy... because of this I used a Super-Glue based 2-part epoxy.
Step 9: You Are Done! Metal Rubik's Cube Complete.
Additional Note: I left the center piece (originally covered by white stickers) out that shows the engraved "Rubiks" logo. While solving I found it had a good impact in identifying that side and it looks cool (my opinion).
