Dodecahedral twisty puzzles

The discoverer of the Dodecahedron was a member of a secretive religious-mathematical cult. He told the public about this odd shape, which was against the rules. The cult therefore killed him. But, as a happy result, we have more puzzles to play with.

The shape of this one is pleasing, but it's extremely easy to solve.

This one is made in solid form by Uwe Mèffert.

This is sold in physical form as the Megaminx™.

Chris Pelley asked me to slice a Dodecahedron this way.
