Interesting but wrong.
Muscle have fibers that contract when stimulated.

Thanks.
I think what really matters is that it works. The muscle takes a semicircular form wich is similar to the form of the muscles on the reality when contracted.

I think if you made a spring that contracted that would be better.

Looks like a muscle to me since it gets shorter and fatter. Since it's an artificial muscle, there is no implied claim that it has to look like a muscle, it just has to work like one, which it does.

P.S. The muscle is hyper-extended so it shakes. Set hinge autoBend to true to stop the shaking. Re-positioning the hinges so that the muscle is longer will also help. Only one hinge needs to be activated, so the code in the outer two hinges can be removed. Bending should be done gradually to prevent the weight from falling out of the hand.

Good job, lololoer!

Just a couple of minor suggestions:
1. Disable the clouds! (I say this to everyone! ) If clouds are not needed in the scene, or if it just doesn't make sense to have them floating by causing distractions, then turn them off!
2. No need to tell everyone that your scene is "buggy". When you do that, you draw attention to the problem rather than to what makes it a good scene! If you plan to improve the scene later, then maybe mention it in the scene description or in a comment.
3. Don't pay attention to others who tell you what is wrong with your scene, or why you didn't do it THEIR way. You do things YOUR way, which is the best way that you know how. And I, for one, have always been impressed with your excellent scenes (especially the animated ones that you've done, such as the one about recycling!). Your scenes are AWESOME!
