We have a bumper post for you today, with a no less than nine dodgems across a pair of fairground creations, each constructed for the ongoing Iron Forge contest on Flickr.

Utilising the LEGO Mudguard Arch ‘seed’ part required by the competition rules, Syrdarian (above) and Dominique Boeynaems‘ (below) ideas have collided, with the pair bouncing to the same conclusion and each squeezing a multitude of mudguards into their bumper builds, from the dodgem cockpits to the roofing.

Each is a wonderful homage to the joy of deliberate gentle collision, and there’s more to see of their brick-based bumper cars at their respective photostreams. Buy your tokens at the fair via the links above – just remember to save the head-on bumping until your last ride of the day!
