From Lightwave 3D website:
The LightWave 3D Group has launched a new design challenge that offers a treasure trove of terrific prizes for the winners! LightWave 3D artists will have the opportunity to participate and win in two design areas - ART and ARCHVIZ. The caveat is that all entries must incorporate Mechanical Spring objects into their designs to qualify and be entered in the challenge. There are no limitations to your designs.
