I just pushed some additional c# minecraft-related projects I've been working on to my github account. In addition to continuing work on LibNbt for generic projects that want to use the NBT file format, I've created LibMinecraft that encapsulates working with Minecraft level files (mclevel format) so it's easier to work with without understanding the underlying way it works. :smile.gif:

My own version of a Minecraft isometric renderer similar to isocraft but with mclevel files instead. In addition to rendering a complete isometric view of an mclevel it will also allow you to render ranges of layers in a map so you can do fun stuff like http://mc.aphdev.com/isolayer/tomb/ (requires canvas so be sure you view it with a current version of Firefox, Chrome or Safari). It also has an option to render top down overviews of maps.
I don't have any binary releases right now for any of my projects but I will eventually.
