Another exciting bout of the Iron Builder contest has just concluded over on Flickr. Brazilian builder Gilcelio Chagas and Indonesian builder Kosmas Santosa battled it out to see who could make best use of the chosen seed part: dark blue half domes. Kosmas ultimately triumphed, but both builders churned out some great MOCs during the month-long contest. Below is just a small sample, in no particular order. Can’t wait to see who they match up for the next round!
