In this curious Liquib scene a house appears to be dissolving into another dimension.  It was actually quite easy to create.  First, a photo of a house was loaded.  Then the Set Mask Stencil/Background option was used to automatically create a grayscale Stencil from the house image, set that Stencil as the current Mask and also set the house picture as the Mask Background.  Another colorful image was then loaded and manipulated with various Tools and Effects.  The result is that only the dark areas of the original house and trees remain unchanged, while the second, altered image shows through the other portions.
