Petal

Petal brings your photos to life with an amazing deep interface. Petal shows your photo in a grid of variations. It's like having a table of large prints to choose your favorite from. Edit your photos on the largest screen, with the highest resolution. Add filters/adjustments and view them in a stack. Even better, view the stack in all dimensions.* *(OK, maybe not all, but at least the three we know of. But seriously, have you ever seen your digital photos blown-up to museum-sized prints, in perfect lighting conditions, and were able to then edit them?)
