Each year Brickfest produces a roomfull of awesome new creations, and this year was no exception. It's going to take me a while to go through all of the pictures to pick out cool new parts usage and building techniques, but this house by Taylor Pluzak caught my eye:
That smooth, curved roof is created by building a wall of 1x2 bricks and bending it slightly. Because of the natural flex of LEGO bricks, the wall bends. The longer the wall, the bigger the curve. I wish I knew how the roof was attached, and how smoothly the walls meet up with the roof. Special thanks to Bill Ward for taking pictures of many cool creations at Brickfest, including this one.
