I found this on my adventures.
When you go to the pages scroll down until you see it.
Not sure it is entirly acurate but!

This two frame gif animation only demonstrates a part of the complex motions associated with Aneros use. It does serve to illustrate the pivoting/fulcrum point of the P-tab but it's usefulness is limited in describing the full range of action/movement due to all the pelvic floor muscle groups. I see it more as cartoon/over-simplification than a realistic representation of the true motion of your Aneros in situ.
Good Vibes to You ! 
Yes I agree but it is the only one of its type I have seen.Would be a good aid for sales on Aneros.com if it was made more accurate and put on the site, one would think.
Yes - at the point where the p-tab is pushed into my perineum, it is the anal and PC muscles that interact to push the aneros against my prostate, rather away from it as here - but I agree that it would be an interesting way of illustrating what CAN happen.
