Meissner Bodies - interactive
Depending on which edges are rounded off, two different Meissner bodies can be created. In the case of the first type of Meissner body, the three edges that meet at one of the vertices are rounded off; in the second type, the three edges surrounding one of the faces are rounded.

The two images are interactive and various manipulations may be performed.
