This sub-menu contains effects that are useful for distorting or convoluting the image.
The following original image will be used for examples:
This effect is used to make part of an image appear close or further away, as if the image had been squeezed.
This will make an image appear as though it is made from a mosaic of randomly shaped crystalline cells.
This popular effect makes an image appear as if it is on the other side of displaced glass, or turbulent water.
This will make the image appears as though it were being viewed through a sheet of frosted glass.
This effect will reduce the detail in the image and give the effect that each "pixel" was much larger.
This applies a transformation between Cartesian and polar coordinate systems (essentially, the image is copied around itself recursively).
This makes the image appear as though it were behind a sheet of glass with articulated tiles.
This effect is used for twisting a portion of the image, either clockwise or counter-clockwise.
