Did you know that there are different layers of snow in minecraft? Only one layer is being used, and it is the flattest one with the code of 78. The other ID's are 78:1, 78:2, 78:3, 78:4, 78:5, 78:6, and 78:7. When you hold ANY of them, they are very glitchy. They flash quickly before its original ID, and 78. They can only be obtained by commands, or any inventory editor such as TMI (too many items). The snow BLOCK (the one that is as big as a dirt block) does not mess up its graphics, and that one is the ONLY snow craftable.
