Background
==========
I bought the 2x2x2 Rubik's cube and needed a way to experiment with it.
Actually, I wanted to find interesting sequences through brute force.
So I wrote this simple simulator in Go.

Description
===========
The logic is simple:
The cube is composed of 8 cubelets.
Each cubelet has an ID and 6 sides with a color each (CubeletColors), 3 of which are visible and the other 3 are internal.
You can rotate any the cube sides (using the rotate func) and see the resulting cube (printAllFaces).
The rotation is implemented as follows:
- get the 4 cubelets on the relevant side
- swap the cubelets to simulate a rotation
- rotate each one of the cubelets (which is performed by swapping the 6 cube sides)

Installation instructions
=========================
Install Go - I used go version go1.0.2 (appengine-1.7.2) on Windows 7
Run: dev_appserver.py C:\google_appengine\2d-cube

Wishlist
========
Implement logic to find interesting sequences
Configure sequences from the GUI
Operate the cube from the GUI
Move to Google Engine
Add an HTML5 frontend
Any other cool features...
