Pyraminx Introduction
This is a simple ball-bearing puzzle actually.  Probably equal to, or slightly more difficult than the 2x2x2 (mini-cube).  It consists of:
6 edges
4 tips
4 centers
These are the centers.  One center can be rotated without affecting the rest of the puzzle. 
These are the edges.  Same general rules apply for pyraminx edges as 3x3 edges.  2 edges cannot be swapped directly without affecting a 3rd edge.  And only even numbers of edges can be flipped.  Don't worry about parities occuring!  Nothing special here...
The trivial tips...There are 4 of them, and a retarded monkey could solve them.  Moving on....
