One of my favourite things to do is perform extreme manipulation on a photo, using filters and layers to produce abstract patterns. I sometimes refer to this process as "deconstruction" because the image is usually warped, distorted and teased apart so dramatically that there is only a nodding reference to the original, often just fragments of structure and palette. When I can, I include that original photo with the design package to show just how much the final design has transformed.
Lately, I have come to realize that working on designs that are very large and rich with detail allows different parts of that design to be placed on different products. This makes such designs very versatile and able to adapt to the demands (usually involving ratio and/or symmetry) of a particular product. See, e.g., "Larval Stage" and the difference between the leggings and phone cases.
