Half Twisting Reverse Frog

This is not the world's most beautiful trick, but is an interesting one to try (particularly if you are a Spiderman fan).

Swing out and turn around. At the platform, lift your legs up and place the soles of your feet on the bar outside of your hands, bringing your butt up as close to the bar as you can. Tip your head back and straighten your back as much as possible. At the catch point, let go with a half twist to catch wrists.

Make sure that you do not kick the bar, and straighten your legs only once you have made the catch and are swinging down with the catcher.
