Holga Toys?

catspaw

I *do* know there are a few Holga users around here, but not sure how far anyone has taken them. I've seen the different filters, lens difractors as well as wide angle available. Most are pretty danged cheap, but together can add up for something that's not much more than artistic fun and still requires electrical tape to use.

Any recommendations or better yet, examples of some of the fun results ?
