We've seen plenty of those tiny lens add-on kits for mobile phones, but never before have we seen the equal of the Phone-O-Scope: 18-55mm glass attached to the iPhone. And it's not wonder, because the process was anything but simple.
ILM Research Engineer Bhautik Joshi disassembled his iPhone only to stuff in part of his DVD player, the laser pickup, which houses three miniature magnifying lenses. These lenses are what made it possible for the iPhone to accept the light/images beaming through the 18-55mm lens, which was carefully positioned through PVC pipe, duct tape and cursing.

The Phone-O-Scope doesn't take especially superb images, and it's a bit clumsy to handle. On the other hand, it's fun to shoot with and produces very analogue (almost Holga-like) results.
