> This looks really cool, but there are dozens of apps and filters out there that do stuff like this, no? Such filters live in 2D, optics in 3D - part of why most filter for things like "bokeh" don't work particularly well is that without an accurate depth map you are guessing or ignoring that 3rd dimension. On the flip side - this stuff is aesthetic, so there isn't one "proper" way to do it.
