You just don't see very many Aztec builds, here on BrickNerd we've only featured a handful. But when they do come along they're usually pretty special, like this one from builder Nuju Metru. It turns out the god Quetzalcoatl was against human sacrifice (why are humans so terrible to each other?) and with the help of some brave warriors is about to put a stop to this rogue priest.  Original linkOriginal author: Tommy

When building giant mechanical machines, many builders are often conflicted with one important question: What's the perfect recipe for an awesome mech? Well according to Marco Marozzi all you need are some big guns and some even bigger legs. I mean, look at those things! One thing for sure, this mech has not been skipping leg day at the gym.

When thinking of dynamite, cooling rods are not the first thing that comes to mind. However, jtooker2 has created a very explosive build (pun intended) by incorporating the dynamite piece as cooling rods in this sci-fi energy plant, which was submitted to the LOLUG’s April Iron Builder Competition.

Ranking quite high on the "sentences I didn't expect to compose today" list is this: Here is a remote controlled LEGO car shaped like a zombie taking a bath with some rubber duckies. I'll let that sink in, then invite you to click through to see more pics of this crazy car by builder Olive_Leaf as well as a video of it in action. Original linkOriginal author: Tommy

There's a moment in every hot rod builder's project where the decision has to be made, what color? In the real world this can be put off and agonized over for most of the project, and consequently make or break it. Imagine having spent years building a car, only to screw it up at the last minute with a terrible paint job. In the LEGO world, that decision has to happen quite early, and can also have dire consequences. Depending on color, finding the parts you need can be quite challenging. So I'm always impressed with a rare color choice, and this purple beast by builder redfern1950s2, is a real eye catcher. Of course purple isn't as rare as it used to be, but it's still very limited in part choice, which makes this hot rod all the more impressive. Original linkOriginal author: Tommy
