iCollide is a simple collision deformer providing a way to create collision effects in Maya without using simulations such as soft bodies, nCloth, or muscle deformers.
iSkin is just something that Ingo developed while on a “deformer creating” roll, I mean, why not indeed. iSkin will allow you to create skin sliding deformations similar to Maya’s slide geometry tool only deformer based. Skin sliding can be controlled by creating a control object that tries to keep the original mesh shape while deforming the vertices over the existing surface. The iSkin attraction feature can be helpful for applying sticky effects to a character, such as the lips of a character as an example.
