A fun side note in the fire saga: the fire texture, upon its introduction to Pocket Edition in v0.7.0 alpha, had a tendency to show a solid color for most or all of its texture. Usually this would be solid black or solid white. In the screenshots in the linked bug report, you can see that there's still some fire texture at the very bottom.
Obviously this is a very low priority thing to do, but it's still a version of the fire texture that appeared in an official version of the game so I consider it worth mentioning. So it might be worth tracking down the source of this bug at one point and seeing if it and the texture it produces can be recreated.
