Xenoflex filtered images combined with Xara's awesome transparency can create some cool effects. The two images (shown on top) have been placed one on top of the other in the image on the bottom left. A Linear Transparency has been applied to the top image creating an unusual  transition.

The same two images have been used on the bottom right with a Circular Transparency centered on the left eye.

Progressively altering a series of images can create some wild animations. You can also create a bitmap image of type and/or other vector images and apply these filters for an unusual effect.
