Jelly Lens sells a variety of little stick-on lenses that you use with your phone’s camera. (It’s a sticky plastic that leaves no residue.) You can get a wide-angle lens, a close-up lens, starburst effect, color filters, kaleidoscope effect, and others. Each lens has a strap so you can keep it attached to your phone. At about $4.00 each, you’re not going to get professional quality optics, but you may find they add some fun to your camera phone pictures. Amazon.com has some of the lenses for about $3.00.
