Recently, I was inspired to make a world/map one can use to show off (and perhaps snap screenshots of) texture packs or perhaps variations on several popular mods. It's something I've been wanting to make for a while, and the one that Calinou recently posted kinda gave me incentive to finally get to work. :-)
This world contains most of the nodes from Minetest's defaults (of course), as well as the moreblocks, moreores, blox, bobblocks, wool, plantlife mods/modpacks, and is done in a style similar to one I saw for Minecraft. More node types will be added as time and my obsessive nature permit. :-)
The default nodes shown here are roughly in alphabetical order from left to right, bottom to top, with the game's default stuff at the bottom, while the nodes for the various mods above those are roughly grouped according to the type or material, color, or whatever is appropriate. I tried to group the various minerals, ingots, lumps, and blocks in a logical manner also. Colors are generally sorted in ROYGBIV order, mostly left-to-right.
These files are meant to used with the latest 0.4 git (or a build thereof) and current versions of the above mods. However, if you're using vanilla Minetest (as opposed to one of its forks), you may have to install most (if not all) of the mods this Test Track supports. Otherwise, Minetest will crash when trying to display the undefined nodes.
Just unzip this file, put the resultant "Texture-Pack-Test-Track" folder into in your Minetest worlds folder (~/.minetest/worlds/ or the Windows equivalent), and then start Minetest and select the newly added world. When the world starts, don't touch the mouse, just turn off the HUD (F1) and chat/debug output (F2), then hit F12 or your OS's screenshot key. If necessary, issue a "/time xxxx" command to set the clock to where you want (e.g. for predictable day or night shots).

Changelog:
2013-04-13: Re-arranged a few things in the test track to account for changes in Minetest and some supported mods since this was last updated. Had to remove the tools and other entity objects from the map because it's impossible to place them anymore. Got rid of the "full" version of the test track, as it is quite obsolete now.
2012-11-20: Added abridged version that lacks support for nature pack and one or two other things, and which uses only the game's default wool mod instead of the older, separate 32-color one.
2012-06-30: Re-created the test track in a whole new world/map - something in Minetest had changed since the last one was released, causing the original one to stop working. In the process, I was able to organize this one a lot better than before, and make everything a little more visible. Not to mention, this version shows off more stuff! ;-)
2012-06-04: Initial Upload, I think.
