Here is a MOC which excited me at first glance.
It is arguably not the best Batpod released to date, but the result is astonishingly original with many parts whose original use has been diverted.
However, the whole may seem a little fragile but I remain thrilled by the ingenuity deployed by the MOCeur.

For reference, Cam M. posted the visual below from which he was inspired for this creation.

Here is a MOC of a machine which is not present in the cinematographic saga but which comes from the video game Star Wars Battlefront. This is a reconnaissance machine, a reduced and specialized version of the A5-Juggernaut that we know well.

Indeed, LEGO has already produced sets with machines from the Juggernaut family (A6): 7261 Clone Turbo Tank released in 2005 and 8098 Clone Turbo Tank released in 2010. We even got the Mini Clone Turbo Tank with the set 20006, set released in 2008.

Davor is doing a fine job here on the tracks or on the armor, the rendering of which is exceptional. The multiple rocket launcher is also very well integrated into the structure. I'm a little less a fan of the cockpit, the finish of which could have been better, especially at the angles.

The whole thing consists of 2400 bricks and you can give your opinion or learn more about the dedicated topic at Eurobricks.

And yes, there are some who have no luck ... Opening of the box of the day, and unpacking. The drama, a part is missing (Cone 1 x 1) while 4 more unused parts on this model are in the bag. and here I am stuck on the construction of this OG-9 Homing Spider Droid, a well-known actor of the Clone wars and that LEGO produced in the system range in 2008 with the set 7681 Separatist Spider Droid.  

So I replace the room with another found in the souk of my son's room to take the photo.

If any of you have any missing pieces, please let us know in the comments.

In the meantime, you can always console yourself with this uninteresting mini-set with the Midi-Scale version of Brickdoctor whose .lxf file can be downloaded at this address: 2011SWAdventDay4.lxf .

Here is an unusual MOC offered by HJR: An AirSpeeder from the'Extended Universe Star Wars and based on a toy dating from 1997 marketed at the time by the Kenner brand.

For the anecdote, Kenner had created this version whose kinship with the classic Incom T-47 SnowSpeeder that we know well is evident on the basis of production sketches made by Ralph McQuarrie, American illustrator who worked a lot on the saga Star Wars.

Other sources indicate that Kenner has decided to market this version identified as a Modified Incom T-47 Airspeeder Prototype to offer within its range a machine that is less expensive to produce and therefore more affordable for its customers than conventional SnowSpeeders.

You will discover many pictures of this machine on this page on Rebelscum.

HJR produces an MOC faithful to the model: the reproduction is of quality and the result convincing. Every detail is reproduced and the wings rotate like on the original toy.

At the opening of the 3rd box of the Star Wars Advent Calendar, many are puzzled by the machine that comes out today ...

It is therefore a Mechno Chair seen in theEpisode I The Phantom Menace. This mechanized mobile projector displays the hologram of Darth Sidious that addresses the Viceroy Nute Gunray on Naboo.

Nothing too exciting, I just tinkered with a Darth Sidious with what I immediately had on hand (You will guess who owns the torso ...).

Attention, for the youngest, it is normal if you did not have the minifigure of the photo in this box, it is not there.

For reference, here is a capture of the relevant scene in theEpisode I..
