Professor's Cube

So my Rubik's collection is finally complete! Yesterday I received my 5x5x5, otherwise known as the Professor's Cube. With the exception of a single small problem I encountered due to the fact that the cube is one bigger than the Rubik's Revenge, solving this one was pretty easy. The problem I encountered though baffled me enough to cause me to search the internet for an answer. Unfortunately, I couldn't seem to find the answer online, but I ended up just solving the cube intuitively today on my own. Like the 4x4x4, solving this cube basically just involves setting it up to function like a 3x3x3 and going from there.

Now, when I say my collection is complete (having all cube sizes from two to five), I should mention that my collection is only complete at the moment. As of this coming Fall, a 3rd party company will be releasing 6x6x6 and 7x7x7 cubes, so I'm sure I'll be picking those up when they're released as well...
