I have animated my spectacular tentacular abstractular doo-hickey.
See my previous entry for a description of this object. This is what happens when I give it a softbody modifier and rotate through 360° over 250 frames at 25fps or, for the non-technically minded, spin a jelly ball for 10 seconds.
It sure looks freaky. I apologise for the bad quality of the video. Youtube didn’t do me any favours with this one. If you’re interested in why the hell I was doing this in the first place, check this thread on the Blender Underground forums.
