We, the Tiles or Studs bloggers love to watch contests and challanges to explore new techniques to build something new. But our favorite contest is absolutely Iron Builder! Cecilie Fritzvold and Chris Maddison battled last month with using new Tile, modified 2x3 Pentagonal piece. Cecilie's final build, Itadakimasu! has a conveyor belt which includes these pentagonal seed parts. This MOC takes place in a sushi restaurant with full of customers. Thanks Cecilie and Chris for their greatest effort in this contest.

Nowadays, Iron Builder Challange shows us good usage of new Pentagonal piece. The contestant, Chris Maddison created a beautiful scenery that use this piece to create a fence for his garden. His MOC, The Flower Garden, is very neat and colorful with different scenery pieces.

LEGO fan and flickr.com member Cecilie Fritzvold has recently shared his impressive MOC for Iron Builder Challange with using new Tile, modified 2x3 Pentagonal pieces. She created a graphic card named IronB BuildForce ABS0937 that shows everything in LEGO form, I guess.

We love flickr's challange groups cause they shows us many different ways to use a piece. Iron Builder Challange is very famous contest which creates showdown of two creative MOCer. This time Cecilie Fritzvold and Chris Maddison do their bests to win the challange. Cecilie recently build a table alarm clock with using Tile, modified 2x3 Pentagonal piece. No time for sleep! is gives us inspiration about the new pentagonal piece.

Nowadays Flickr grows their popularity in AFOL community with coolest challanges which started at flickr groups. Flickr.com member and LEGO Fan Joseph Z. is shared his latest creation Modern Bedroom which is built for ABS Challenge. He used lime green telephone piece 9 times in this MOC as drawer pulls, alarm clock bells and feet of bench. I mostly liked the design of the alarm clock and window shades.

Iron Build Challange which was very popular last month because of awesome creations of Jonas and Tim Schwalfenberg. This month KOS Brick and 2MuchCaffeine has been challenging. Rod Gillies (aka 2MuchCaffeine) created an iron and ironing table with Paint Roller Brush Handle seed part.

LEGO fan and flickr.com user Doctor Mobius shared this amazingly detailed mad-max style truck in his photo-stream. This car was built for the Lugnut's 100 Ways To Win! build challenge. The build is based on the Hot wheels model spoiler sport. I especially like that the figures are brick-built. A victim is bound on the tail section which I find very creative. 

The car is full of small details including chrome-coated pieces, weapons, chains and bombs.

LEGO Fan and model car master builder Aliencat! shared this great pickup truck Custom 1952 Ford F1 in his flickr.com photo-stream. The car features an opening hood and doors as well as an engine and decorated interior. The creator also added a surfboard and a sunbed which make this MOC outstanding. This creation is built for the 100th LUGNuts challenge.

The Ironbuilder challenge between Tim Schwalfenbeg and Jonas continue at full speed. The creativity in this challange is really impressive therefore we continue to post MOC's from it time to time. As his turn Tim built this amazing classic fire truck as his seventeenth build where he used the metallic pin element in various place like the latter, bumpers and lights. I especially like how the front windscreen is placed using the base parts of lever element.
