Quite a few of the objects in this
picture were created in Truespace and a few in Bryce. You could do
a lot of this in a freeware modelling program or in Bryce itself if
you were creative and inventive. A few functions such as lathing,
and extruding makes it easier to create forms such as springs and
threaded screws, and warping objects such as the paper to create an
organic effect...The device at the foreground actually has hydraulic
parts, springs and bolts, but Iam afraid very little of it showed
up.
