These terrific LEGO creations will make your heart sing [Gallery]

[All week long SideQuesting celebrating LEGO, one of the greatest toys of the last 100 years and a true bastion of creativity. Every day we’ll have original content submitted to us by great writers. Look, here’s one now!]

We’re nearing the end of LEGO Week here at SideQuesting, but we still have a few things left to show you. Several of my office coworkers sent in photos of their incredible sets, both retail and unique builds. Have a look below and enjoy!

Up first, Contributor Jay Zadina showcases his work. Jay is a professional 3D modeler, so he loves getting his hands dirty with intricate details. The Arctic set is full of vehicles and buildings, and two LEGO polar bears apparently having too much fun in the background.

Jay loves big trucks and Australia, and so this ginormous land train was a natural fit. All of it is self-designed, as you can’t possibly find a set with this many identical pieces!

Who DOESN’T love this legendary Millennium Falcon? This set is worth over $4k on eBay, and will only grow in value. Jay added support underneath as the beast was so large that its weight was causing the entire underside to sag!

Sherry Sabbagh is a well-regarded Color & Materials Designer in the design world, and was kind enough to share with us her kids’ passion of LEGOs. Her son, Blake, is huge into Bionicle, and regularly mashes up his figures.

Natalie Simovski, of NFGRAFX, also has a pair of boys that love LEGO. Here are some of their creations, and the obvious creative mess that those ideas come from!

A very cool shuttle design, and the functioning arm that catches satellites.

Here’s a great way to make a birthday announcement!

Thanks to everyone who submitted photos for the gallery!
