The keys aren't integers 0...n here, they're 1, 2, 3, 4, L, R, T, D,
TL, TR, BL, BR in the code, so a dict is preferable to a list.
Incidentally Katie: is 'D' a typo? It should be 'B' for consistency.
Also, functions can be passed arguments, and doing so is preferable to
passing information via global variables.
So
def LoadMaterial(loader):
...
sand = LoadMaterial('Sand')
Is a lot better than
def LoadMaterial():
... code using 'loader'
loader = 'Sand'
sand = LoadMaterial()
