iColorama 12

Form/warp. One setting, warping by stroking with one finger. Opacity reduced in this image so the original is also visible.

Form/flip. Three settings. Two sliders: moving the 'Feature' slider moves the image, as above.

Form/crop. Does what it says on the tin. Six presets plus free crop.

Form/deforms. Nine options, two-four sliders. In some of these images, opacity is reduced.
