Scopes are an OC classic. (Young, usually attractive) Photographers run up and down the beach, and offer to take your picture for free, then you go to the studio to view the photos in little "telescopes" that can be hung from a keychain, rearview mirror, etc. A nice alternative to pictures being shoved in a box that you'll rarely look at.
The photographers are usually well trained, and the pics generally come out very well--they go through a variety of poses, so you end up with a lot of options. They can also be a little pushy, however, so if you don't want your pics taken, your best bet is to put on sunglasses and feign sleep.
You're not obligated to buy the scopes; if I go through the trouble of having my pics taken (rolling around in the sand, etc.), I usually buy one or two. They are fairly reasonably priced, though I haven't bought any in a few years, and they usually offer packages, ex: buy 4 and get a discount.
Overall, a cute souvenir for your trip!
