Maybe your shelter in minecraft is already a megafortress, your farm is self replenishing, and you've mastered the art of redstone CPUs. If so, congrats - we'll be asking you for help soon!
If not, and you'd like some help learning some of the coolest tricks when building, reply with what building skills you most want to learn. Examples - simple homes, basic redstone circuits, mansions, skyscrapers, stadiums, cannons, mine cart rollercoasters, etc.
I built the MC Instructables mod (http://www.minecraft...ool-structures/) to hopefully get some assistance from the best builders in minecraft. Using the mod, great builders can capture or record their creations, so that others can play back step-by-step in-game instructions to build the same. Blocks you need to place appear transparently in the world until you drop a real block. As you build each level, the next level of instruction appears. Like Lego instructions IN minecraft. Pretty cool, no?
Replies to this post will be super useful in building a library of blueprints to ship with the mod.
