I don't recommend scrapping working code, but in the future, you might want to think about doing something a little more ruby-flavored. Something like, oh, maybe this....


def HexCell < Array
	blah blah
end

ary = HexArray(3,4)
=> (Array of HexCells)
>>ary[2,3].neighbor(:upperleft)
=> HexCell at [2,2]

Delta would be defined like this:

	Delta={:center => [0,0], :upperright => [0.5,-1], :right => [1,0], :lowerright => [0.5,1], :lowerleft => [-0.5,1], :left => [-1,0], :upperleft => [-0.5,-1]]
