The deadline is only a few hours away (midnight tonight) for the Mini Castle Contest VI. If you build something today you can still get it in. The two most recent entries are Spartacus' Cliff Castle and Bartosza6m's Castle of the Rising Sun.
Automatic translations are tricky, but it looks like this Hungarian site held a micro Star Wars contest. A couple of my favorites include a clever use of the tiny-fig trophy and a small rendition of an AT-AT.
When LEGO opens new stores, they usually produce an exclusive model as a giveaway at the opening event. This past Saturday a new store opened in Nürnberg, Germany, and the exclusive was a micro version of Nürnberg Castle.
It's been a long time since I've done set focuses, and I haven't written about Set 10214 - Tower Bridge since it was released. This set has been available via LEGO.com for the last month or so. Coming in at US$240 and 4287 pieces, this is a massive set. Just the 556 tan cheese wedges alone have many excited. Another unique part is the pair of unique shields. As a castle guy I'd love to outfit a faction with this heraldry, but these will run you at least $2.50 on Bricklink. Ktraphagen did a great job of documenting the building process and you can see a video with the set's designer. ADHO16 made a virtual version.
Porschecm2 came up with a great part usage in Solus Saxum for the Mini Castle Contest. Those trees are made from a decorative spine piece that shows up in one Ben 10 set, so you can't really be blamed if you didn't know what that was.
Here's Micro City County Fair, a BrickCon entry by Amanda Payton. The top of the merry-go-round is nicely designed. Looks like the Ferris wheel is functional, too.
