Have you heard of Jelly Lens? I've had some for a couple of years. They're meant to fit over the lens of a camera. I no longer have a point-and shoot with a small lens, so I use mine with my camera phone.
On the back of the lens is a thin plastic cap. When you pull off the cap, you'll see a tacky jelly-like ring. This is how the lens sticks to the camera. Lens styles include: wide angle fisheye, close-up, polorizer, starburst, spark, heart frame/blue filter, star/sepia filter, stretch effect, vignette, 6 image kaleidoscope, and 3 image kaleidoscope. I kind of want the spark filter next.
Here's an example of the wide angle:
And here are some examples of the kaleidoscope:
What do you think? Would you buy any of the Jelly Lenses?
