There are so many completely novel flavors and shades possible with the apparently blank canvas that is snake (I'd rather see it called Nibbles...). I certainly like the philosophy names. Even more, I appreciate that the game somehow behaves in a ways that, in each case, can only be responded to with a bit of delight, and a sense of "I don't know what I was expecting ..."
It really made me think about how important a well-structured philosophy really is in creating a game, story, interface, and a lot of other things! One needs to understand their own view of the universe in order to create another one effectively, I imagine.
