A prop you can drive into, or grab a node and bash a car with it.
Made from a clay sculpture I created a while back.
Also I give permission to anyone who wants to use the Jbeam, matieral, info file or model for whatever they want to create with any of them. Its a simple Jbeam but if it can help, have at it. Just change author name. The Jbeam is about the size of the default Blender Box. Should be pretty easy to replace the head with something the same size. Its not a perfect box. Its more like a half sphere, half box. Control B I believe to see the beams.
