Motion Madness

4090-1 Creator 2003 243 parts 11.2% Easy

Embark on a journey of mechanical discovery with LEGO Inventor Motion Madness (4090-1), a set from 2003 designed for dynamic construction. This set encourages builders to craft original contraptions that truly move. The included Idea Book provides detailed instructions for six unique models, alongside nine additional concept starters to spark further creativity. Builders can construct models that fly up a string, ride a bike across the floor, or move along a wire, setting wheels in motion with their custom designs. The diverse assortment of elements, including essential Technic gears and axles, allows for the creation of intricate, functional mechanisms. Experiment with different build configurations, watch your creations perform their designated actions, and then reconfigure them into entirely new, moving machines.
