A yin/yang symbol, simple csg.
A spiky sort of star, from some early playing with csgs.
Slightly more complicated: a standard sort of milk carton thingy.
Somewhat neat: a hinge object.
A flourescent lamp, based on some idle doodlings. This is actually three
objects, a base/upright, an extending arm and the lamp shade, so positions
can be adjusted.
A cagedoor door, using the hinge shown above. This is two objects, the cage
door and the cage wall, so the door can be opened and closed. Animating
this, however, uncovers yet another bug in sceda I haven't yet tracked
down... :(
