Most new smartphone cameras have decent resolution but bare-bones features. Photojojo recently introduced two add-on lenses that let you take wide-angle and fisheye photos with any camera phone. The lenses attach magnetically to small adhesive-backed rings that stick to the back of the phone. We didn't see a dramatic difference in the wide-angle shots, which are just .68 times wider than standard phone photos, but we like the funky fisheye images.
COST: $40 for both
